I am trying to figure out a chi square problem, and I keep getting stuck. The problem reads: A researcher tested single mosquitoes from five different locations for the presence of a particular virus and obtained the following data:
Location A B C D E
w/ virus 3 7 9 11 3
w/o virus 26 32 21 16 30
First I performed a chi square test about found that the data indicate there are significant differences between the locations.
Specifically, I found that my test statistic, T=12.88, X^2=9.488, and my p-value=0.01187.
However, I have no idea what those differences are. I don't know how to describe the patter of differences/determine which locations are significantly different from each other. I looked into doing a Tukey's test but it doesn't really make any sense with this problem (I think). I don't know if it makes sense to just do a bunch of separate chi square tests between all the variables. Any help would be much appreciated!
