Hi everyone,
I am writing a paper for publication. This is my first time doing a survey study, and also my first time working with categorical data (I, like many people unfortunately, have learned statistics bit by bit, as I have needed it in my research). The journal I am submitting to requests reports of effect size. I mostly used Pearson's chi-square for my comparisons, but in some cases, my 2 x 2 contingency tables had low expected values, and so I used Fisher's exact test. For the chi-square tests, I calculated the phi coefficient as a measure of effect size. For Fisher's exact test, I have read that odds ratio is an acceptable effect-size measure. Two questions, then:
(1) Can I report phi for some of the tests in my study and the odds ratio for others, or should I have a unique measure of effect size for all of the tests in my study?
(2) How do I report an odds ratio as a measure of effect size in my paper? (I have not been able to find this information in any APA format guidelines online).
Thanks in advance
