Deciding whether two populations have the same distribution uses the test for:
AHomogeneity
BIndependence
CGoodness of fit
DSingle variance
Answer & Solution
Correct answer: A. Homogeneity
1. The three chi-square tests answer three different questions.
2. A different test, called the test for homogeneity, can be used.
3. It draws a conclusion about whether two populations have the same distribution.
4. The test of independence instead looks at two variables within one population.
