Contingency table not including all values
Posted: Thu Jan 05, 2023 9:01 am
Hi,
I'm doing a chi-squared/Fisher's exact test with a data set of 26 samples in group A and 21 in group B. Looking at the contingency table however it only includes 21 values, i.e. it doesn't include the 5 last values from group A. Is that how the contingency table/program works or is there something wrong going on? Shouldn't the analysis include all 47 values? I mean, the results differs quite a lot depending on what values are put in row 22-26 (thus not being included in the analysis).
I'm quite new to all statistics and been stuck trying to figure this out for days now, so I truly appreciate some advice here!
Thanks and all the best,
Emma
