Q1) Dr. Joanne Wood recruited people with high and low self-esteem to participate in a study of positive self statements. Half of the participants from each group were randomly assigned to repeat to themselves the statement "I am a lovable person" every 15 seconds for 4 minutes. The other half of the participants were randomly assigned to wait silently for the 4 minute period. Then, all participants rated their mood on a questionnaire (low values indicate unpleasant moods and high scores indicate pleasant moods). Low self-esteem participants who repeated "I am a lovable person" scored 11. High self- esteem participants who said "I am a lovable person" scored 31. Low self-esteem participants who sat in silence scored 17. High self-esteem participants who sat in silence scored 25. Here is the bar graph illustrating the results: 35 O I am lovable 30 silence 25 20 15 10 low self high self esteem esteem Here is the table showing the averaged scores for each condition: I AM LOVABLE SILENCE LOW SELF ESTEEM 11 17 HIGH SELF ESTEEM 31 25 a) What are the IV(s) and levels of each IV? State whether each IV is manipulated between- or within-subject? b) What is the DV? c) For each independent variable, state whether there is a main effect or not and then describe the effect. In order to be considered different, in this example, the marginal means should be greater than 1 from each other. d) State if there is an interaction and then describe the interaction supporting your answer. In order to be an interaction effect, in this example, the difference in differences should be greater than 5
