1. ### Calculating and Reporting Effect Size for Fisher's Exact Test?

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...
2. ### Compare odds in two fisher tests

Dear all, I performed 3 fisher tests from data implicating in each test the same two sets (A & B) with two different sets in each case (A&B vs C&D, A&B vs E&F, A&B vs G&H; tables below). Fisher tests for the three sets gave low p values with odds of 6.6, 3.6 and 2.5. I need to know if the...
3. ### Logistic Regression: interpreting an interaction term

Dear Forum, This topic has been covered a lot here and in other forums, but I have yet to find a clear answer to this particular problem. I'm trying to understand how to interpret the odds ratio of an interaction between a categorical variable with 6 levels (6 similar products) and a...
4. ### Convert odds ratios and beta coefficients to a comparable effect size

Dear all, First a short introduction to my study/review/meta-analysis. The purpose of my study is to systematically review longitudinal evidence on the association between psychosocial work characteristics (i.e. job demands, job control, social support) and sleep, since cross-sectional...
5. ### Odds ratios in hierarchical linear modelling

Hi, I am currently running a model which tests differences between the success rate for males and females in passing a test. In this model passing is coded as 1 and failing is coded as 0. Males are coded as 0 and females are coded as 1. Below is the output that I got when I tested this...
6. ### Different between "X % more likely" vs. "X times more likely"

I often see something like "smokers are 10% more likely to get cancer than non-smokers." Is this equivalent to saying smokers are "10 times more likely"? I think this is a probability vs. odds vs. percent increase thing, right? Say we have a 2x2 table: Cancer No Cancer Total...
7. ### Extremely large Odds Ratios?!

Hi, I've conducted a binary logistic regression with 1 independent variable (Type of property: flat/maisnette, terraced, semi-detached, detached and other) and dependent variable (1= distraction burglary, 2=non-distraction burglary). Apparently the model is significant, yet each of the...
