ANOVA applied to examination scores Available to Purchase

The paper re‐examines data published by Johnnie (Work Study, 1996) on the performance of two groups of bank workers on four examination subjects. This leads to a discussion of the application of the analysis of variance in contexts where there is one within‐person factor (for example, examination subject), one between‐group factor (for example, urban or rural location of person), and persons constitute a random factor within the group factor. The analysis of Johnnie’s data leads to a conclusion that differs from the original – that the two groups differ in mean score on one of the examinations.
