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).Which statement best sums up this part of the output?
A)I need to transform all of the items.
B)There were significant differences between the mood induction conditions on two items: 'I am a worthless piece of scum' and 'Bodily fluids are nasty'.
C)There were significant differences between the mood induction conditions on three items: 'I am a worthless piece of scum','I would never eat catfood' and 'Bodily fluids are nasty'.
D)We can assume homogeneity of variance because most items show non-significant effects.
