Should I include the 35 items? Or the 5 scales together? Or should I compute a "Total score" scale? I always get different data.
Thank you kindly for your help.
In SPSS, you can go Analysis-descriptive statistics-frequency . and move all items to variables box. and click on chart , put tick on histogram and show normal curve. or you can go Analysis-descriptive statistics-explore and do normality test.
Since you are not doing a multivariate analysis, I will advise you treat each variable one at a time. That is you perform the S-W normality test for each of the variables. This is very simple on SPSS. Just follow the descriptive statistics concept on SPSS. I hope this help
Dear Veronika,
I suspect that it is the scales that you should be testing for normality, not the items. You can put them all in the Dependent variable list.
There are two main ways scales are constructed:
I would recommend using the latter if you are creating your own instrument. If it is someone else's instrument they should tell you how to construct the scales.
