Play B's win rate looks worse overall but better in every segment. Which test?
Test selectionMediumProblem. Two sales plays were used last quarter. Overall, play A won 26% of its opportunities and play B 21%, and a chi-square test on the 1,600 opportunities says B is significantly worse (p about 0.01).
