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.
A) The type of mood induction had a significant effect on responses to all nine items.
B) The type of mood induction had a significant effect on responses to at least one of the nine items.
C) The type of mood induction that a person had could be determined from a linear combination of responses to the nine items.
D) The type of mood induction had a significant effect on responses to more than half at least of the nine items.
