three companies‚ located in different regions‚ are equal to each other during the holiday shopping season. 2. If we have three or more population means to compare‚ why can’t we test them two at a time until we exhaust all possible combinations? Testing two at a time would be very time consuming. Using an ANOVA test allows greater effiecencey than using and reusing a two-sample t-test when dealing with three or more populations.
