A psychologist was interested in the effects of different fear information on 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 who 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 account for the natural anxiousness of each child, a questionnaire measure of trait anxiety was given to the children and used in the analysis.

The analysis used is Analysis of Covariance (ANCOVA) because it is comparing the effects of three different fear information on children's beliefs about an animal while taking into account the natural anxiousness of each child (trait anxiety) measured by the questionnaire. ANCOVA is used when there is a continuous dependent variable and one or more continuous independent variables (in this case, fear information and trait anxiety) that may be related to the dependent variable.
