Abstract

Many researchers want to compare means of different groups after or before
an omnibus test but they often have problems in selecting an appropriate method
since there are many comparing methods for different conditions. Therefore,
this article presents how to select an appropriate method for comparing means of different
groups before and after an omnibus test, and also gives some general suggestions for
selecting an appropriate method to suit best certain testing conditions of the groups;
otherwise, using an inappropriate method may give the researchers different results.
