Consider the following well-known example from Winer (1971). An experiment is conducted in which six subjects are divided into two groups according to the method of calibrating dials (‘Method’). There are four shapes of dials (‘Shapes’), and each subject gets four accuracy scores – one for each shape. This is a two-way ANOVA with repeated measures on one factor (the ‘Shapes’ factor). Conduct the appropriate ANOVA analysis. Interpret your results.
