Procedure Practice

This web page gives you practice in identifying the correct statistical procedure, given the stated hypothesis.

Purpose

Welcome to the page that helps you determine the important characteristics of the research hypothesis. In practicing here, you will gain experience in:

The Problem

Think about the hypothesis. Ask the important questions. What is the unit of measurement? What is being measured on each unit? Are we comparing two variables? Are we comparing means? proportions? Answer these questions. Get to know the hypothesis.

Now that you have your answer, click on the button corresponding to your choice to see if it is the correct answer. Here is the research hypothesis.

HR :  The average total cholesterol of Americans is greater than 150 mg/dL.

The unit of measurement is the American person. On each American, the total cholesterol is measured. Because there is just this one group, and a hypothesis is made about the average value, this is a one-sample t-test. This hypothesis is equivalent to

μ > 150
