ChiSquared Analysis
Hi all,
First post here. Apologies if this post isn't in the right place, I haven't got a feel for this place yet.
I'm pretty confused about how to go about performing a pairwise chisquared analysis of a table of percentages I have (see image).
Basically, I just need to compare each column to Class A (Class A vs Class B, Class A vs Class C) using a chisquared test.
Am I right in assuming that the right process is to compute the mean percentage of the two columns I'm comparing, then doing the chisquared calculation [=(xAVG)^2/AVG] for each percentage, or am I way off?
Additionally, to do a chisquared analysis of the whole table, do I do the same procedure as above, but use the average percentage of the whole table?
Thank you very much in advance for any help. I've always had a hard time understanding stats, and after trying this for a while, I've become frustrated.
