More Hypothesis Testing
Introduction
This example demonstrates how to test the null hypothesis that two variables are
uncorrelated, reinforces the concept of degrees of freedom, and demonstrates, in a
concrete way, what is meant by an asymptotically correct test.
About the Data
For this example, we use the group of older subjects from Attig’s (1983) spatial
memory study and the two variables age and vocabulary. We will use data formatted
as a tab-delimited text file.
