The tests discussed so far that use the chi-square approximation, including the Pearson and LRT for nominal data as well as the Mantel-Haenszel test for ordinal data, perform well when the contingency tables have a reasonable number of observations in each cell, as already discussed in Lesson 1.

WebThe Fishers LSD test is basically a set of individual t tests. The only difference is that rather than compute the pooled SD from only the two groups being compared, it computes the pooled SD from all the groups. If all groups are sampled from populations with the same SD, using all the data to compute the pooled SD gives a more accurate value ...
