Question

A market researcher wants to see if two different stores have the same distribution of sales throughout the year. What type of test should he use?

Short answer

The market researcher will use the homogeneity test.

Step-by-step solution

Concept introduction

A hypothesis is a reasonable assumption for a behaviour (plural hypotheses). The scholarly approach involves that an assumption be validated before it can be deemed a factual prediction. Technical speculations are mainly influenced by past results that cannot be fully addressed by established scientific findings.

Explanation

It could be used to see if two populations have the very same distribution or not.

The test statistics for a testing of homogeneity and a testing of independence are generated using the same method.

The independence study checks at whether two variables are mutually excluded.

The market researcher is determining whether or not two stores have the same sales distribution throughout the year. As a result, the market researcher will use the homogeneity test.
