Psychology IA - how does inferential statistics work?
Guest posted a topic in PsychologyHello!! 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
Lab Report Biology IA: Statistical Tests
Sarthak Garg posted a topic in Biology and ESSHello 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.

Psychology IA- Inferential Statistics
par posted a topic in PsychologyHi guys, I am in the process of finishing my psychology HL IA.

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.
IA IA Inferential Statistics
Arctus98 posted a topic in PsychologyI 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.
