What analysis should be done to see if the mood inductions had an effect on responses to these nine items?
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.
