IS‘25: Procedure Practice

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:

parsing the hypothesis for important details
determine the unit of measurement
determine the correct parametric test given the hypothesis

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.

H_R : Heavier people tend to run slower than lighter people.

The unit of measurement is the person. On each person, two thing sare measured: speed (numeric) and weight (numeric). Since we are hypothsizing about the relationship between two numeric variables, a correct test is the correlation test. The hypothesizd relationship is negative, since increasing one decreases the other. This hypothesis is equivalent to

ρ < 0
