# likert scale formula

Likert scale, rating system, used in questionnaires, that is designed to measure people’s attitudes, opinions, or perceptions.Subjects choose from a range of possible responses to a specific question or statement; responses typically include “strongly agree,” “agree,” “neutral,” “disagree,” and … It’s part of a school project, as you said. It’s amazing to me that you have stayed on this discussion thread since 2013 ! there are 5 treatment groups (6 mice each group) are compared, 2 controlled groups (positive controlled and negative controlled) and 3 experimental groups (50%, 75%, 100% solution). Thanks sir. Since the questions are connected to 1 concept, is it possible to use the mean? thank you. Thanks Erica! A key difference is that Likert items are bivalent (i.e., they extend in two directions) and symmetrical, which is not the case with your item. – I do not know why the responses are skewed, and cannot advise you further without consulting your data, questionnaire and research questions. I’m afraid that I cannot help you with this question because you have not told me what your research question is, i.e., what you’re trying to find out. I wish you all the best in your further research. :) How could I justify the use of Friedman’s instead of ANOVA, or in other words, what makes you argue that Friedman’s is a safer choice? Also would it be wrong to replace the missing values with the ‘Persons mean’ or ‘Item mean’ as suggested by Downey & King 1998.Also how about multiple imputation? Unfortunately, this problem had gone unnoticed by the editors of the collection, and by the peer-reviewers employed by the press. Field, A. hi. If the responses are very different, you should then try to account for what might be causing the difference. You can find instructions on how to do this here. Mine is quantitative and 5 Likert scale data. Dear Achilleas Likert scale data can, in principle, be used as a basis for obtaining interval level estimates on a continuum by applying the polytomous Rasch model, when data can be obtained that fit this model. The main objective of my research is to look at the relationship between these two concepts/constructs. I am asking respondents the degree with which they agree to a few statements, viz. Point Value Statistical Range Descriptive Rating No worries! 167-4 = . To calculate the median, you will have to arrange your responses in order of magnitude e.g.. Then you start crossing out one number from the end of the list and one from the beginning, and repeat until you are left with a single number (or two). The data is 4 point likert scale > extremely satisfied to extremely dissatisfied). You might also need to compare responses given by different groups of your sample, e.g. strongly agree=1. The most widely used is the Likert scale (1932).eval(ez_write_tag([[250,250],'simplypsychology_org-medrectangle-3','ezslot_9',174,'0','0'])); In its final form, the Likert scale is a five (or seven) point scale which is used to allow the individual to express how much they agree or disagree with a particular statement. (10+50)/2=30) using Wilcoxon signed-rank test. 2) I would like to check if changes occur during 3 time points. The study seeks to analyze the integration of risk reduction in the science curriculum along prevention and mitigation, preparedness, response, recovery and rehabilitation. Is there another formula that should be used? Do the findings add significantly to the existing body of knowledge?). I am sorry, I do not provide AMOS tutorials in this space. My study only involves 14 students and this step of classifying them into 2 groups based on their level of motivation is just the first step in my data analysis. If I understand correctly, you have two questions: (a) what kinds of statistical procedures you need to run in order to analyse your data, and (b) how to do these procedures (i.e., what ‘statistical tool’ to use). i use five point likert scale (yes, occutionnally, no, dontknow and not applicable and five point strongly agree… strongly dis agree ). Another thing, it gets me confused when I try to interpret the mean as some studies treat the mean of 2.3 as uncertain. New York: Wiley. Achilleas Kostoulas is an applied linguist and language teacher educator. It is a meaningless research question; and if it could be answered by anything as crude as statistics, it would have been answered anyway. When you say Likert scale is it an actual scale or just one Likert item? Thank you again, Dr Kostoulas! It is one of the most widely used question types in a survey. Agresti, A., & Finlay, B. Research MethodAttitude MeasurementLikert Scale. I feel like your the correct person to ask this. My sincere gratitude for your quick reply to my concern. Likert items and scales produce what we call ordinal data, i.e., data that can be ranked. Can I insert the mode/central values in SPSS? You are assuming that the ‘distance’ between ‘strongly agree’ and ‘agree’ is the same as the one between ‘agree’ and ‘neutral’ (also that its is half the distance between ‘strongly agree’ and ‘disagree’, and so on…). A Likert scale is a psychological measurement device that is used to gauge attitudes, values, and opinions. I am afraid I can’t really answer this question without knowing more about your data. I have a sample size of 500+ . I believe that ecological questions are the most important issues facing human beings today. When you say Likert scale is it an actual scale or just one Likert item? But do have a look at this post, which may be of help: http://achilleaskostoulas.com/2014/12/15/how-to-summarise-likert-scale-data-using-spss/. Many researchers tend to use Likert scales to do things that they were never designed to do. Likert scales are very frequently used to measure constructs like satisfaction rates, attitudes towards different things, and more. Besides, as you will read in the blog post above, and in many statistics manuals, calculating the mean for Likert scales is dangerous statistical territory. That rubric consists of 4 questions that measure different aspects of the same skill. However, you will likely need to estimate the central tendency and dispersion for each item: you can find some ideas here. However, if only the first and the last response options are labelled and the respondent is asked for the strength of their reported opinions/ feelings (e.g., on a scale of 1-6, where 1=very bad and 6=very good), then the intervals can be assumed to be equal. I would be grateful if any one help me in this context. i need ur ideas on the tools to be used in Experimental Research entitled: ANTI-PRURITIC ACTIVITY OF PLUMERIA ACUMINATA (KALACHUCHI) BARK LATEX IN ALBINO MICE WITH INDUCED LOCAL PRURITUS. Rather, this is an ordinal (or arguably interval) scale. What I ended up doing is normal descriptive analysis for each statement by showing the frequency of every answer for each statement. Hi. My variable will be age, field of study and year of study. The responses were: Strongly agree = 42; Agree = 104; Neutral =32; Disagree = 14, Strongly Disagree = 0. 3. From 3:41 until 4:20 represents (agree). The median is a type of average value, like the mean, except that it shows the number that is exactly in the middle of the data, i.e., at the same distance from the highest and lowest value in the dataset. This post has been prompted by an edited collection that I was recently asked to review. If you must compute the mean, which I strongly recommend against, you can use the formula described in the post. No, it’s not. However, unlike a Likert-item, there are more-or-less identifiable start- and end-points, so it’s less of a stretch to argue that the anchor points are equidistant (spaced at equal intervals). I am afraid that I cannot be more specific, as I do not have information about your research questions or the dataset. (eds) Handbook of Disease Burdens and Quality of Life Measures. to 2.00 is (disagree); I wonder whether I should write to the university and tell them that they are wrong. As I need to know use what test suitable to compare my demographic profile of respondents with my dependant variables? 1 Which method should I use to present findings? Likert Scales have the advantage that they do not expect a simple yes / no answer from the respondent, but rather allow for degrees of opinion, and even no opinion at all. If you think they can, do so at your own risk. PS. So how to analyse this set of data? Maidenhead: Open University Press. etc, Well, that would depend a lot on what you’re trying to find out, wouldn’t it? Elementary level – 1 We are using likert scale with two different categories of questions which is safety and technical itself, where each category has its own questions. Highly Ineffective 1 2 3 4 5 6 7 Highly Effective, Weak feedback 1 2 3 4 5 6 7 Strong Feedback. Sometimes, sets of similar items are dispersed in the same questionnaire. To me this makes a lot of sense that an individual receives for example a score of 3,4 on intrinsic motivation. It consists of 30 items. For example, each of the five (or seven) responses would have a numerical value which would be used to measure the attitude under investigation. You could condense the responses to ‘positive’/’negative’ and do item-by-item cross-tabs, but I suspect that the low number of respondents and the large number of variables will prevent you from getting anything really conclusive. SPSS, or any equivalent statistical package, will generate both values for you, and I believe MS-Excel also contains a function for calculating these values. A Technique for the Measurement of Attitudes. Hello Dr Kostoulas! The scale you are describing is not a Likert Scale. 2. You reverse the coding for the negative statement(s). The problem with Likert items is that many researchers –including the ones whose paper prompted this post– tend to use them in order to do things that they were never designed to do. It is often used to measure the attitudes of respondents, asking them to what extent they agree or disagree with a particular question or statement. About your questions: 1) Strictly speaking, your rubric still produces ordinal data. I will do that. I already did analyse the cornbach alpha and found α = .818. Hi Sir, can use mean using this scale A Likert scale assumes that the strength/intensity of an attitude is linear, i.e. For better or for worse, research methods are too diverse and too specialized for reviewers to have more than a passing acquaintance with most of them. the respondents view the questions as similar. But thank you for the confirmation. I am interested to know the level of awareness of my students with regards to earthquake, fire, flood and typhoon along the four thematic areas : prevention and mitigation, preparedness, response, and recovery and rehabilitation. But clearly, the 7-point scale is also designed as a ‘Likert-type’ scale. It is the most widely used approach to scaling responses in survey research, such that the term (or more fully the Likert-type scale ) is often used interchangeably with rating scale , although there are other types of rating scales. But, like I said, a Friedman test might be a safer choice. plz tell me the difference b/w likert scale and ordinal scale as i have to defend myself and also share how to calculate ranges for means of a likert scale…. In other words, while you can find an average of 1,2, and 3, you can’t find an average of “agree”, “disagree”, and “neutral.” plot(as.likert(x)) Both likert and plot.likert work by calling the as.likert function on their argument x. I don’t know how to look into this the right way and what kind of analysis I need to use to get the right information. In: Preedy V.R., Watson R.R. 2. So should I consider it as a simple rating scale or as a likert scale? To put it in the simplest terms possible: Ordinal data cannot yield mean values. 1. What is the best way to analyze the data ? MAL says. Here is how to easily find the right linear transformation to convert one Likert scale to another. Some of the other means are over 3.0 but the bar graphs related to them are neutral as well. But an argument came up that the mean and standard deviation was the appropriate technique for the kind of data I collected. And if it is a likert scale, should the analysis be done by taking the median? Blunch, N. J. This is best done in two stages. Thanks. You have stated that “The mathematical model needs these assumptions in order to work, but they are simply not in the questionnaire design. It could be anything, really, from 15 (+- 25, 95%) to 532 (+-1, 99%). for convenience. Likert scale data can, in principle, be used as a basis for obtaining interval level estimates on a continuum by applying the polytomous Rasch model, when data can be obtained that fit this model. and 3= not implemented yet You should also take a look at the list of additional resources. (1997). 4-like much Five questions ask variants of the same thing, and the scores are summed. Likert scales are clearly ordered category scales, as required for correlational work, and the debate aong methodologists is whether they can be treated as equal interval scales. Each item/question is stated this way: At least college graduate – 5 You see, my group are doing research about city bus users’ experiences on the safety and technical perspective. Unless otherwise indicated, all rights reserved. Is there a connection between mean and the bar graph percentage and can I link the two? it is possible to use to reject and acdept the mean points below and above. You should use the median instead. 3-dont’t know As regards the second part of your comment, you seem to be missing that the question has no operational definitions of ‘effectiveness’ or ‘method’, it assumes that methods are applied consistently across time, and presupposes somehow controlling for any learning that takes place outside the classroom, among other problems. Characteristics of Likert scale. A Likert scale instrument produces interval-scale numeric values. Our formula for determining this is. My feeling is that for this kind of calculation to work, you need to assume that the ‘distance’ between “strongly disagree” and “disagree” is the same as the one between “disagree” and “not sure”, and so on. You could treat your data as nominal, if you want, but an argument can be made that these responses can be ranked: someone who ‘agrees’ has stronger beliefs than someone who is ‘uncertain’. it depends on what you are trying to find out with your research. It is typically a five response category scale ranging from “strongly disagree” to “strongly agree”.The purpose of a Likert scale is to identify the attitude of people towards the given stimulus objects by asking them the extent to which they agree or disagree with them. 3 0.0109 I am using an eating behaviour questionnaire with 1-5 Likert response scale. thanks :). Those who are not familiar with the fascinating minutiae of quantitative research can find a discussion of Likert scaling and ordinal data in the section that immediately follows. If you can convincingly argue that this is how your respondents interpreted the scale (perhaps the wording of the question encouraged them to think so? To view this video please enable JavaScript, and consider upgrading to a I don’t mind having it in my inbox. Overall, there is no single ‘right’ method. They would therefore pronounce something along the lines of: ‘Our study revealed mild disagreement regarding the palatability of fish and custard (M=3.5)’. If you make this assumption, and I don’t think you should make it, then you can use the formula described in the post, which produces a mean value of 3.94. can I ask where to find the explanation about this scales? on a continuum from strongly agree to strongly disagree, and makes the assumption that attitudes can be measured. For my study, I am more interested in classifying the students into 2 groups and not 5 groups. attitude toward drug consumption) in an experiment with 80 subjects. 9-point Likert scale: A 9-point Likert scale is quite uncommon, but you can use it by adding two more answer options to the 7-point Likert scale question. I am not sure if your responses to the questions that were asked by two other persons on 26 March 2014 @ 01.49 and 16 March 2015 @ 17.58 applies to the question I have asked below. 5-like very much If you think that they can (and some statistics guidance websites might encourage you to think so), you can still take your chances. The Likert scale is after Rensis Likert, the social psychologist who invented the use of scale points in … hi sir.im conducting a survey for my final paper.Im using two questionnaires-one is a three point likert scale and the other one is a five point likert scale.My study is about learning styles and language learning strategies.How am i supposed to find out the extent of relationship between these two variables and the extent by which my subjects utilize these variables? intervals between values cannot be 5-strongly agree Therefore, the mean (and standard deviation) Can I use the mean scores for each subscale for further analysis? The final score can have a value between 0 and 15. (Jamieson, 2004). Applied multivariate techniques. Second, I intended using the above 7-point scale to produce interval-level data analysis rather than simply ordinal level data analysis. on a continuum from strongly agree to strongly disagree, and makes the assumption that attitudes can be measured. i cinduct my research work in the topic of corporate social responsibility of the hotels. You can make sure by calculating a variable called Cronbach’s alpha. What you can do is describe the distribution of answers for every question, by showing the bar chart, and a table with the absolute number and percentage for each response option. The last update was on February 2020. So, rather than double checking on such matters, we tend to focus our feedback on more substantive aspects of the research (e.g., Are the claims commensurate to the scope of the study? I’ve just tallied the results and I don’t know what to do next. Hi. I already put them into SPSS and measured the median of each scale. 2-Point Likert scale example for agreement: This question is the simplest Likert scale question example where there’ll be just two options, such as agree and disagree as two poles of the scale. Prima facie, I see no statistical reason why not to use two groupings rather than five, if it makes more sense in your study. 1. Starting with a value of 0 would be more intuitive, but involves unnecessary work… either way, make sure you explain what you did in the methods section, and maybe add some reminders when you are describing the results. Each variable should have several values (one for each possible answer, such as ‘strongly agree’, ‘agree’, and so on). Likert scale. Thank you for a useful and informative post (which I’ve just discovered) – though I disagree with your strong view of Likert scales always eliciting ordinal data. Good luck with your project. 3-moderately like Thank you so much for your time. And even if we forced them into the questionnaire, that would constitute a gross distortion of psychological attitudes and the social world to fit our statistical mould.” Can you kindly elaborate on this or direct me to the appropriate resources on which these statements are based? 3 – Somewhat Significant Can I work with that having in mind that the objective of the study is to observe relationships between different variables (use ANOVA; correlations, etc)? Respected sir ,Hi thank you sir for your response,still I want to know few more things ,I am student and fresh in research work.I have administered Liker t scale to 100 teachers .I have collected data.Please tell me how to measure median and mode,and how to express variability in terms of the range and inter quartile range.And how to display data in a dotplot. That number is your median. In case of doubt, if go for non-parametric procedures, just to be on the safe side. You should normally define a different variable for each questionnaire item. 41 0.1496 Nominal/categorical data are data that are categorically discrete (e.g., baby names, places of birth etc.). I’m doing this experiment on liking and I used likert scale to gather data. Calculating average scores is one of them, and here’s why it’s wrong: Imagine that ten survey participants were asked about their attitudes towards fish fingers and custard. hi sir archilleas! Although attitudes and feelings cannot be measured with the same precision of pure scientific variables, it is generally accepted in the social sciences that self-reported data can be regarded as continuous (interval) and used in parametric statistics (Agresti & Finlay, 1997; Pallant, 2007; Sharma, 1996). A Likert scale can be considered as a grouped form of a continuous scale, and so you just treat the variable as if it were continuous for correlational analysis. web browser that Specifically this is the statement of my research They just mentioned that their Universities lecturer taught them to do it this way. I feel that my data should be nominal. But medians are a good alternative. In other words, while you can find an average of 1,2, and 3, you can’t find an average of “agree”, “disagree”, and “neutral.” In addition to measuring statements of agreement, Likert scales can measure other variations such as frequency, quality, importance, and likelihood, etc. 3.01 until 4:00 is (agree); Dr Kostoulas, thank you very much! How should I interpret my data? Chances are that you landed on this page looking for information on Likert scales and averages. However, you might find some help in this post. scales have a rank order, but the I am having 355 sample size and want to compare the reasons of visit to a fast food outlet. Very well written. First, in Power Query I copied the query, Chose Columns to include only the ID and the Likert Items, and then unpivoted the Likert scale so that I had a zillion rows of Attribute/Value pairs. https://www.simplypsychology.org/likert-scale.html. This means that each question placed next to the Likert scale will look as below: Sample statement from SUS How to Calculate Your Usability Score using SUS. If you want to study the effect in real life I would use mixed efffects modelling and data from standardised tests (like PISA) combined with observations and self-reports by the teacher.. You may find that I have referred to Norman (2010) elsewhere in this blog, and while I think it is a reasonably well-argued line of thinking, I am not sure how it contradicts what I have written here. To do this, you need to check the ‘chi-square’ box in the ‘Cross-tabs: statistics’ dialogue box (the second one in the webpage that I linked). Yes sir ,It will be helpful for me as I am doing MED.That information will be help me to complete my dissertation. A Likert scale is a psychometric scale used to represent people's opinions and attitudes to a topic or subject matter during research. Moreover, the ranks of a Likert scale could extend infinitely on both directions, which is not the case here. var pfHeaderImgUrl = 'https://www.simplypsychology.org/Simply-Psychology-Logo(2).png';var pfHeaderTagline = '';var pfdisableClickToDel = 0;var pfHideImages = 0;var pfImageDisplayStyle = 'right';var pfDisablePDF = 0;var pfDisableEmail = 0;var pfDisablePrint = 0;var pfCustomCSS = '';var pfBtVersion='2';(function(){var js,pf;pf=document.createElement('script');pf.type='text/javascript';pf.src='//cdn.printfriendly.com/printfriendly.js';document.getElementsByTagName('head')[0].appendChild(pf)})(); This workis licensed under a Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 Unported License. Assigning a cut-off reduces that range of evenly-space values to two categories. Cut off point means to identify the activities of the hotels based on the responses,add the five scales (5+4+3+2+1÷5=3).BELOW 3 taken as negative and rejected above 3 teken as positive and accpted .based on this i identify the activities of the hotel corporate activities. I have data on an ordinal scale: 0, Never; 1, Rarely; 2, Sometimes; and 3 Often. Burns, N., & Grove, S. K. (1997). A likert item refers to a specific statement that a respondent is asked to evaluate in a given survey and on the other hand a likert scale refers to the table as a whole. You’d only do mean score ranking if you thought that the anchor points are equidistant, i.e., something ‘poor’ is 20% the quality of something ‘excellent’. This does not mean that such procedures are optimal practice, and Norman does not make this argument anyway. You can find the information you asked for in the post above, or in this post. (2019, August 03). You may also want to look at the following posts: k ər t / LY-kərt) is a psychometric scale commonly involved in research that employs questionnaires. Now, I like to add few questions under one of the sub category. So, in this case, I decided to let it pass. Hi Judith :) You’re right, it’s probably OK. It assessed learners’ views towards second language learning on five areas, namely self-image, inhibition, risk-taking, ego-permeability and ambiguity tolerance. I am using likert scale in a survey as mean score from 4.01 until 5.00 is (strongly agree). Hello, thank you for your life-saving post! Thank you, Sir. 5 4.20 – 5.00 Excellent $\endgroup$ – Glen_b Mar 5 '19 at 2:34 $\begingroup$ I have added more details of my hypotheses into the original post. The mode is the easiest to calculate: it’s just the option that most people chose. A Likert scale enables respondents to choose from a linear set of responses that increase or decrease in intensity or strength. If you treat the data as nominal, the only measure of central tendency you can use is the mode (i.e., you can only report which answer is the most common). This is done by crosstabulating: creating a contingency table where one variable (e.g., Grade) forms the rows and another (e.g., questionaire item) forms the columns. 1=fully implemented It has been revised several times since, with a view to making it more useful to readers who are looking about statistical advice. I am unable to use the total of scores of each subscale as there are missing data points in some questionnaires. https://achilleaskostoulas.com/2013/09/09/four-things-you-probably-didnt-know-about-likert-scales/, what will be a sample size of a population of 550. In most cases you will find that the difference is small in practice, but -in my opinion- it is theoretically important. Likert scales are symmetrical, around a central point. You can confirm whether the difference is statistically significant by running a test called ‘chi-square’. Various kinds of rating scales have been developed to measure attitudes directly (i.e. For instance, Vigor was measured with 3 items i.e: I feel strong and vigorous when I’m studying (Vigor1, vigor2 and vigor3) and what is the best way to calculate the value for Vigor.
