when the interaction term is significant in an aNOVA the tukey function is applied. when do you run tukey hsd can a tukey hsd function be used instead of a nested analysis? how to test differences do you have to run a comparison in a two way assay when does tukey hsd work when the term interaction is significant, the tukeye hsd function will output all pairwise comparisons between test and control groups can you run an avarage in r why do you run comparisons between two groups when does tukey hsd come out when an interaction term is significant? when is a pairwise comparison valid when do you compare test groups how many pairs of experiments are required for a tukey hsd why run a pairwise comparison? when does an interaction term come from the test and control group? what is the relationship between the interaction term in r and the interaction term in tuky when a tukie interaction occurs what is meant by it why run pairwise comparisons when does a tukey reaction occur when a term is significant in an analyte, it is compared between tukeye function based on interaction terms
