Textbook Problem

  1. 1. A researcher completes a chi-square test for independence and obtains x2 = 6.2 for a sample of n = 40 participants.
  2. 2. If the frequency data formed a 2 X 2 matrix, what is the phi-coefficient for the test?
  3. 3. If the frequency data formed a 3 X 3 matrix, what is Cramer's V for the test?

a.

To determine
The phi-coefficient for the test.

Explanation

Given info:

X2=6.2,n=40

Calculation:

The formula for calculating the Phi-coefficient is,

ϕ=(X2n)

Substitute the values in

b.

To determine
The value of Cramer’s V.
