1. Cohen d greater than one

I think there are correlations between the other genes. After the issue I had with this first case, I stopped my work ... Thanks for your help.
2. Cohen d greater than one

I am doing a genetic study but tried to present my problem in a simple way. I have seven genes (my seven binary variables). I picked one gene and want to see how correlated are my six other genes with it, in 500 animals (my sample). I want to rank these genes by their strength of correlation. I...
3. Cohen d greater than one

Just rephrase my question appropriately, supposed I get more data and solve the balance of the data, would chi square be a valid test or should I still use logistic regression?
4. Cohen d greater than one

So chi square is not the right test for my data? Any reason?
5. Cohen d greater than one

I wanted to see how the occurrence of var3 depends on var1 or var2. Thanks
6. Cohen d greater than one

I used chi square as a test of independence to examine if the null hypothesis can be eliminated.
7. Cohen d greater than one

Thank you for your prompt reply. Yes all my variables are binary. So, I should shouldn't use Cohen d, I just need to report p? What about chi square, is it the right stat for my data?
8. Cohen d greater than one

Hello, I am comparing two discrete variables (where the values can be one and zero only) with a third one using chi square test and Cohen d for the effect size. In my comparison, I found that my Cohen d was greater than one, with a significant p-value. I searched the web and found a vague post...
9. Which statistics test to use?

Thank you very much for your help.
10. Which statistics test to use?

Dear all, I am working on a project about a diagnosis system where I have two scenarios. In the first I have binary data like: highTemp 0 1 etc. where zero indicate normal temperature and 1 indicate high temperature. I want to correlate this with a class whose values can be one of three...
11. Chi square effect size

Thank you for your reply. The phenomenon I am observing is rare in both populations by nature. So I am not surprised by the small percentages. What I would like to say is, despite this phenomenon is rare (in both populations), it is more frequent/likely in one of them (again the probability...
12. Chi square effect size

Hi, I have the following data: # successs # non success population1 12 2293 population2 82 4926 I ran chi square test on the table above using the tool: http://vassarstats.net/newcs.html. I got the following results: chi...
13. Correlation with nominal variables

Thank you for your reply. If I understand well, I should use chi square in both data set not with the second one only. Thanks again.
14. Correlation with nominal variables

Dear all, I have two data sets and I would like to measure correlation between variables. In the first data set I have three classes: c1, c2, c3. My classes are representing the difficulty level of an exam and I converted them into numbers such as 1 (easiest), 2 midlle, and 3 (hardest). The...
