Summarize your Likert scale data using descriptive statistics. These variables will be their own category on the graph. The variability or dispersion concerns how spread out the values are. The Likert scale lists the categories of the psychometric scale such as "Strongly Agree," "Agree," etc. While Likert scale variables usually represent an underlying continuous measure, analysis of individual items should use parametric procedures only as a pilot analysis. The responses range from one extreme attitude to the other, while always including a neutral opinion in the middle of the scale.

Developed in 1932 by Rensis Likert 1 to measure attitudes, the typical Likert scale is a 5- or 7-point ordinal scale used by respondents to rate the degree to which they agree or disagree with a statement ( table ). Further analysis appropriate for ordinal scale items includes the chi-square measure of association, Kendall Tau B, and Kendall Tau C. . In an ordinal scale, responses can be rated or ranked, but the distance between responses is not measurable. This is not a valid method for analyzing Likert scale data, which are ordinal in nature. The dependent variable stfhlth was measured using a 11-point Likert scale ranging from extremely bad to extremely good and is being treated as continuous for the purposes of this example. $\begingroup$ I agree with Mr. Jeromy Anglim's justification on the use of mean (i.e., weighted mean to be exact) as the most reliable unbiased more descriptive interpretation of ordered categorical variables such as the use of Likert scale where each of the data points contribute to the final average.

The respondent answers by choosing from a set of answer options (see Figure 1). Run a frequency distribution on each of your variables. The basic choice is between a parametric test and a nonparametric test. The central tendency concerns the averages of the values. Often times, researchers go right into Inferential Statistics and Skip the Descriptive Statistics, since it is less informative. All in all, with too many questions to be assembled in a single analysis, one should reflect about parceling as well. So far I have reversed the order of certain questions and calculated mean scores, and then used a . That said, and only trusting in what was stated in #1, sometimes we see Likert-scales being transformed into scales ranging 0 to 20 or 0 to 100, hence producing a variable with the mean value of the questions selected. 3.

Because Likert item data are discrete, ordinal, and have a limited range, there's been a longstanding dispute about the most valid way to analyze Likert data. The easiest way to accomplish this is by using an online calculator for t-test comparing averages or means. . the mean is the best measure of central tendency. A Likert-type scale involves a series of statements that respondents may choose from in order to rate their responses to evaluative questions (Vogt, 1999). Numerical coding of the responses allows researchers to analyze Likert scale data with descriptive and inferential statistical methods. Are they? Often times, researchers go right into Inferential Statistics and Skip the Descriptive Statistics, since it is less informative. Once you have the mean values for both, perform the t-test.

(The primary focus of this course is on questionnaire/survey data and Likert scales; for a more detailed look at data analysis in SPSS, our courses descriptive and inferential statistics in SPSS courses are recommended) This course is . Highlighted the descriptive statistics you can obtain using ordinal data: Frequency distribution, measures of central tendency (the mode and median), and variability (the range). But scholars increasingly challenge their foundations. A Likert scale assumes that the strength/intensity of an attitude is linear, i.e. Forty-nine percent of the 706 articles were reports of quantitative research with at least one variable measured by a Likert-type scale.
