Question

A friend gives you the following Fs and decisions made.

For each one, decide if the decision appears to be correct?

Explain why or why not. * Do NOT provide critical or table values as explanations.

1. F(2, 63) = .10, not significant

2.F(3, 85) = -1.70, not significant

3. F(1, 120) = 64.32, not significant

4. F(5, 70) = 1.00, significant

Answer 1

1. F(2, 63) = .10, not significant
the p-value = 0.9050
Correct decision

2.F(3, 85) = -1.70, not significant
F value cannot be negative
Incorrect decision

3. F(1, 120) = 64.32, not significant
p-value = 0.0000. As p-value is less than 0.05 it is significant
Incorrect decision

4. F(5, 70) = 1.00, significant
p-value = 0.4243, As p-value > 0.05, insignificant
Incorrect decision
