Question
On the basis of the ouput below, Field and Lawson (2003) reported the effects of giving the same children aged 7–9 years positive, negative or no information about novel animals. This variable was called “Infotype” (levels of Infotype were entered in the following order: positive information, negative information, no information). The gender of the child was also examined. The outcome was the mean-centered time taken for the children to put their hand in a box in which they believed either the positive, negative, or no information animal was housed. The assumption of Sphericity is not violated.
Contrast analysis was performed on these data (levels of Infotype were entered in the following order: positive information, negative information, no information). Using the SPSS output given above, calculate the effect size (r) of the interaction between the contrast between negative information and no information and gender. Round your answer to four decimal places.
Solution
You use the formula for the r of the contrasten
r = sqrt [ (F(1,dfR)) / (F(1,dfR) + dfR) ]
F(1,41)=0.163 and dfR=41. The outcome is 0.0629.
