Minuet Posted October 25, 2011 Report Share Posted October 25, 2011 I can reassure you that, out of all the IAs I've done, Psych IA is the worst...hahahaha. Anyway, I'm doing my experiment on the levels of processing. I have three groups, and I'm comparing how many words each group recalled. I'm almost done, but I'm stuck with the inferential tests. My book states that I have to choose one out of Chi-squared, Mann Whitney-U, and Wilcoxon (I think). None of those 3 seem to suit my data because they all require two groups. So, I'm confused. I think my data is ordinal. I'm not really sure about that, either. Help would be much appreciated Reply Link to post Share on other sites More sharing options...
blindpet Posted October 25, 2011 Report Share Posted October 25, 2011 If your design was independent measures (one group did only one condition) then since your data are interval/ratio (e.g. time, weight, height) you would use multiple independent t-tests or an ANOVA. Since ANOVA is pretty advanced I recommend you do the multiple t-tests. The tests you mentioned are for ordinal (rankings like 1-7) and nominal data and are not relevant to your data set. You might want to limit your groups to just a deep and superficial level of processing and ignore the third group. Reply Link to post Share on other sites More sharing options...

There are two groups, where one group is presented with a list of 20 words faster than the other group. Would I be doing the multiple t-test, too? I am done with my report, just have this one part left. Reply Link to post Share on other sites More sharing options...

Do I have to do it manually (and put the calculations in the appendix), or can I just use the calculator on the net (with no calculations in the appendix)?

Do I have to do it manually (and put the calculations in the appendix), or can I just use the calculator on the net (with no calculations in the appendix)? I would put the calculations in to be safe, the syllabus says that the appendix should contain the raw data and calculations. I don't know how detailed these calculations need to be though. Try looking at some sample IAs to get an idea, there are some on my blog and on this forum. Reply Link to post Share on other sites More sharing options...
