You are the best lecturer I ever met online and on face to face. Slow but sure with precise explanation, you use the words and voice which the deaf can hear and the blind can see. Would you post a detailed lecture note on how to analyze Likert scale data on SPSS? eg. provide an example on how to analyze 5 level of agreements (5 Strongly agree to 1 strongly disagree).

I'm glad you found the video helpful. Constructing and analyzing a Likert scale is a big issue and I like your idea of making a video about it. It'll go into the queue of videos I have to make. Actually both a Likert scale (a combination of several Likert statements) and each Likert score from each statement can be analyzed using correlation (one scale vs another scale) or t-test/ANOVA (do groups differ in their average scale vaules?) and I have videos on that already.
