Question

Levene's test was non-significant, F(2, 12) = .82, p = .47, and so the results must be treated with caution.

The type of therapy administered had a significant effect on stress levels, even after baseline levels of stress had been accounted for, F(2, 11) = 5.98, p = .017.

The type of therapy given did not have a significant effect on stress levels, after baseline stress level had been accounted for, F(2, 11) = 5.98, p = .52.

The type of therapy administered had a significant effect on stress levels, even after baseline levels of stress had been accounted for, F(1, 11) = 23.16, p < .001.

a)

Levene's test was non-significant, F(2, 12) = .82, p = .47, and so the results must be treated with caution.

b)

The type of therapy administered had a significant effect on stress levels, even after baseline levels of stress had been accounted for, F(2, 11) = 5.98, p = .017.

c)

The type of therapy given did not have a significant effect on stress levels, after baseline stress level had been accounted for, F(2, 11) = 5.98, p = .52.

d)

The type of therapy administered had a significant effect on stress levels, even after baseline levels of stress had been accounted for, F(1, 11) = 23.16, p < .001.

Participants were randomly allocated to one of two stress management therapy groups, or a waiting list control group. Their baseline levels of stress were measured before treatment, and again after 3 months of weekly therapy sessions. Based on the output below, which of the following statements is the most accurate?I Tests of Between-Subjects Effects Levene's Test of Equality of Error Variances Dependent Variable: Stress level after 3 months of therapy Partial Eta Dependent Variable: Stress level after 3 Type IlI Sum Squares months of therapy 04.932 17.996 14.4722.482 135.062 23.164 34.8875.983 831 184 678 521 314.796 14.472 135.062 69.774 64.138 1523.000 378.933 a.

Explanation / Answer

Answer is a)

Levenes test was non-significant , F(2,12)=0.82,P=0.47 and so the result s must be treated with caution .
