Exam 17: Multivariate Analysis of Variance Manova

A psychologist was interested in gauging the success of a mood manipulation during one of her experiments. She had three groups of participants who underwent different types of mood induction: disgust mood induction, negative mood induction and positive mood induction. After the mood induction, participants were asked to endorse nine statements relating to their mood (on a 5 point Likert scale from 1-disagree to 5-agree): (1) When you're smiling the whole world smiles with you, (2) I love the pretty flowers, (3) I could never touch a dead body, (4) I would never eat cat food, (5) If someone served me monkey brain soup I would vomit, (6) I feel fed up, (7) Bodily fluids are nasty, (8) I could not drink from a glass that I'd used to catch a spider, (9) I am a worthless piece of scum. What analysis should be done to see if the mood inductions had an effect on responses to these 9 items. Part of the SPSS output is below. Which of the following statements best summarizes the output.

In a study on the influence of exercise type on pulse rate and dependence on dietary preference, the following table details Tests of Between-Subjects Effects. Source: http:/ / ssc.utexas.edu/ docs/ stat38.html This same study produced the following output for dietary preference by exercise type by intensity, which can be viewed below. How would this information best be reported? Multivariate tests of significance (S = 2, M = -1/ 2, N = 701/ 2) Source: http:/ / ssc.utexas.edu/ docs/ stat38.html

Which is not a test that can be used to assess multivariate differences in MANOVA?

Which of the following is not an assumption of MANOVA?

In MANOVA the effects of covariates can be evaluated by

A researcher wanted to know if people on different university courses has different personality traits. She asked people studying psychology, dram and maths to complete two dimensions of a personality test, a self-efficacy dimensions and a self-discipline one. Based on the results given in the following tables, what conclusions can be drawn? Tests of Between-Subjects Effects a R Squared = .004 (Adjusted R Squared = .002) B R Squared = .008 (Adjusted R Squared = .007) Multiple Comparisons Scheffé Based on observed means. * The mean difference is significant at the .05 level.
