This is for my Msc in Psychology dissertation - and I am still easily confused when dealing with stats etc - but am trying to educate myself. However I haven't found any examples of this happening to others.
I used a sample size of 320. The other two standardized tests used both had excellent Cronbach alphas, both greater than 0.8. They were the Mindful attention awareness scale and Rosenberg's self-esteem Scale.
I have checked that my scoring and the questions were correct - which they appear to be.
Any guidance or help is appreciated. Thank you in advance.
Kind regards,
Alex
Hello Dr Annear,
Thank you for this. That is very helpful and I will indeed look into these things.
Kind regards,
Alex
If you have examined each variable and the scoring is correct (i.e., no reversed items, no problems with missing data), then you find out which items have low correlations with the rest of the set. If you are using SPSS, it will do this for you using the "Alpha if item deleted" option. Otherwise, you need to look at a correlation matrix among the items to see which ones are generating relatively low correlations.
