What analysis has been used?
A psychologist was interested in the effects of different fear information in children’s beliefs
about an animal. Three groups of children were shown a picture of an animal that they had
never seen before (a quoll). Then one group was told a negative story (in which the quoll is
described as a vicious, disease?ridden, bundle of nastiness that eats children’s brains), one
group a positive story (in which the quoll is described as a harmless, docile creature that
likes nothing more than to be stroked), and a final group weren’t told a story at all. After the
story children rated how scared they would be if they met a quoll, on a scale ranging from 1
(not at all scared) to 5 (very scared indeed). To control for the natural anxiousness of each
child, a questionnaire measure of trait anxiety was given to the children and used in the
analysis. The (edited) R output is below. The next two questions relate to this output.
a. Analysis of covariance.
b. Independent analysis of variance.
c. Repeated measures analysis of variance.
d. Mixed analysis of variance.
e. Factor analysis.
