I'm working on some research and would like to ask for some help regarding the use of Eta-Squared. Our school's review board recommended the use of the statistic for my study which is looking to correlate nurse job satisfaction, occupational stress, and reason for seeking work abroad. My confusion stems from how the review board redesigned my tool. For example, for occupational stress, it looks like this:
Am I correct to assume that I am computing this on a per item basis and not on a per respondent basis? Because it seems the review board wants me to see the effect size for each item rather than a comparison between respondent A's stress levels and reason for leaving 'levels', for example.
Also, would it be prudent to include a correlation statistic (maybe Pearson R)? Because it seems I already assume that these items are already significantly correlated with leaving one's job, which doesn't seem right from a statistical point of view (assuming I mean).
Oh, also I'll be using SPSS v23.
Any advice would be most appreciated. Thanks!
