Evaluate the F test statistic for the following data where n

Evaluate the F test statistic for the following data, where n=4 for each sample

Group 1

Group 2

Group 3

Group 4

Sample Mean

6.6

3.4

3.0

1.2

Sample Variance

5.35

1.35

2.5

2.65

.

Solution

F1 = VAR1/VAR2

= 5.35/1.35 = 3.96

F2 = VAR3/VAR4

= 2.5/2.65 = 0.94

F3 = VAR4/VAR1

= 2.65/5.35 = 0.495
