A researcher is interested in whether people are more likely to recycle when other people are watching. They created three conditions: one in which several people were around and watching folks by the recycling bin and trash can (N = 15), a second where there were a few people around and watching (N = 15), and a third condition with noone around (N = 15). Number of items being recycled were counted during the study for all the conditions. Which of the following is the correct degrees of freedom within groups? 31=2 3 14+14+14=42 15+15+15=45 An interaction effect can be identified by dividing each cell mean by its marginal mean. dividing each cell mean by a weighted marginal mean. . conducting a series cft tests. looking at the pattern cf cell means. A researcher is investigating the effects of exercise and taking naps on overall positive mood. He finds that exercise (vs. no exercise) is associated with higher ratings of overall positive mood. He finds that taking naps (vs. not taking naps) is not related to ratings of overall positive mood. Lastly, he finds that there is no difference in the mood of people who exercise and take naps compared to those who only exercise. Assuming that any difference is statistically significant, which of the following best characterizes these results? 1 main effect and 1 interaction effect 2 main effects and 1 interaction effect 1 main effect and 0 interaction effects 0 main effects and 1 interaction effect 0 main effects and 0 interaction effects 2 main effects and 0 interaction effects Variable 1 A B C Variable 2 Y 10 Assume any differences are statistically significant. How many statistically significant effects are there? 0 main effects and 1 interaction effect 1 main effect and 1 interaction effect 1 main effect and 0 interaction effects 0 main effects and 0 interaction effects 2 main effects and 1 interaction effect 2 main effects and 0 interaction effects Using the information below, what is the GM for a planned contrast between group 1 and group 4? M1 = 7.53 M2 = 4.24 M3 = 6.92 M4 = 5.18 7.23 2.35 6.36 5.89 A research group wants to test if alcohol intake (none, up to two drinks, more than two drinks) and the use of anxiety medication (none, low dosage, large dosage) affect driving ability independently or if they interact in explaining driving ability. Which is/are the independent variab|e(s)? All options above Alcohol intake and anxiety medication dosage Driving ability The interaction of alcohol and anxiety medication
