Question 2

What type of hypothesis test should be used for the following scenario? What assumptions should be met for the hypothesis test results to be trusted?

Solving mathematics word problems can be particularly difficult, especially for elementary school children. Educational researchers wanted to investigate a combination of techniques for helping student to master these problems. The researchers wanted to investigate the effectiveness of small-group tutoring. But they also wanted to examine the effectiveness of a classroom instruction technique known as "hot math." The hot-math program teaches students to recognize types or categories of problems so that they can generalize skills from one problem to another.So, in addition to testing the effectiveness of tutoring versus no tutoring, they wanted to examine whether using traditional instruction or hot-math instruction was more effective.
