Problem Set 4.1: Critical Value

Criterion: Explain the relationship between k and power based on calculated k values.

Instructions: Read the following and answer the questions.

Work through the following and write down what you see in the F-table. This will help familiarize you with the table.

The F-table: The degrees of freedom for the numerator (k 1) are across the columns; the degrees of freedom for the denominator (N k) are across the rows in the table. A separate table is included for a .05 and .01 level of significance.

Increasing the levels of the independent variable (k):

Suppose we have a sample size of 24 participants (N = 24). Record the critical values given the following values for k:

	.05	.01
k = 2 k = 4 k = 6 k = 8
