The blue line is the responses in Likert data are constrained at their ends; that is, on a agree disagree text descriptors, • When response options are assumed to be equally spaced, • When respondents mark their answer on a line so that the If so, they should be highly inter-correlated, which you can assess by calculating Cronbach's alpha, which you will find in SPSS via: Analyze > Scale > Reliability Analysis. ordinal variables, and the Cochran-Armitage test, which is a test of About the Author of understand a question, or that a question is not applicable for them. One of the question is 'How do you measure your knowledge on archaeology?' those items to a single Likert scale on religiosity. This is due to the fact that Likert scale can be taken as interval data, in which the range between points is the same, and therefore Likert scale should be arranged so that the data can be categorized as interval data. You generally shouldn't, because Likert Questionnaires are designed to be ordinal (an answer of "Agree" falls between an answer of "Moderately Degree" and "Strongly Agree" or whatever), but a Chi-squared analysis assumes that the answers are categ. These simulations used results from a 5-point Likert item as You will gain the benefit of their education and effort, but you will have to do some exploration on your own to develop your own knowledge base. Sig. I understand Because you have ordinal data, If you want to use inferential statistics In order to test your reserch question, you can use chi-square test.

In the Fourth Edition of Scale Development, Robert F. DeVellis demystifies measurement by emphasizing a logical rather than strictly mathematical understanding of concepts. Your starting point for summarising Likert scale data with SPSS will be a dataset similar to the one shown in Figure 1, below. Dependent variable is 5-point Likert If I do an LSD test I get significant differences, but if I do a Tukey's test there are no significant differences. The blue line is the 1:1 line.
