I am going to take a statistical course in the next couple of months, but unfortunately my questions cannot wait till then as I am analyzing my data now.

Questions A:

2 groups. Group 1: n = 180. Group 2: n= 25 (I think this can be classified as categorical, e.g. distribution of gender in each group).

For this analysis I have used Chi Square. Do you agree? Since it is a 2x2 categorical data)

Question B:

5 groups.

Group1: n = 178 (e.g. 170 +ve, 8 -ve)

Group2: n= 15 (e.g 5 +ve, 10 -ve)

Group3: n = 15

Group4: n = 8

Group5: n = 24

Each group represent a test result, and we are comparing the test results to see if it correlate with the diagnosis.

e.g. 5 ways of measuring blood glucose levels, we want to see if there are any difference between these groups.

Can I use One way ANOVA?

I very much appreciate the help.

Thanks
