Hello!! I am writing my psychology IA right now, but now I'm at the result section and I don't understand a thing! My teacher does not explain this well, and he doesn't seem to be certain about what he's doing. There was actually a few people last year who failed their psychology, mainly because of their IAs so I'm a bit terrified! I'm a HL student, so I will need inferential statistics but how does that actually work?? For example, my teacher said I should use the General Linear Model, but I don't know if I'm allowed to use that.. I haven't found anyone who have used it before, but

Hello I am currently finishing up my IA for Biology HL. I have 5 conditions one of which is control. Each with 5 trials measured over 4 time periods. With 3 dimensions to my research, I was wondering what statistical tests I should use. I was thinking of doing ANOVA and HOC test to check the difference between the conditions with each trial. 4 times ofcourse due to 4 time periods. Is this a good choice? What else should I use. Can I simply use a online calculator for this test, reference it and give the table that shows the results and then explain what the results tell me for the ANOVA and th

Hi guys, I am in the process of finishing my psychology HL IA. Our teacher is new to the IB and she has no idea about inferential stats so she is not even checking it for us as she doesn't know how to do it and it is up to us. I have managed to do the Wilcoxon test using an application online however I don't know how I am supposed to explain it and relate it to my data and hypothesis. My experiment was on the stroop effect and I used a repeated measure design which is why I chose to do a Wilcoxon test. Can someone please help me with this. Thank you all in advance.

I have finished my Psychology HL Internals, did a study based on Bransford and Johnson's study on schema activation and memory recall. My teacher had suggested that I use Mann-Whitney U test for inferential statistics, as my data was ordinal in nature. Admittedly, I don't have a considerable understanding of inferential statistics yet. I recently saw that for recall from memory, the data collected was actually interval data, and that I should use Wilcoxon t-test.
