Aa Aa 1. In a repeated-measures analysis of variance... In a repeated-measures analysis of variance, how does the magnitude of the mean differences from one treatment to another contribute to the F-rata? The mean differences add to the numerator of the F-ratio. The mean differences add to both the numerator and the denominator of the Fratio. The mean differences add to the denominator of the F-ratio. The mean differences are subtracted from the numerator of the F-ratio.

1) The following data were collected from a repeated-measures study investigating the effects of 4 treatment conditions on test performance. Determine if there are any significant differences among the four treatments. State the null hypothesis. If you determine a significant treatment effect, use Tukey's HSD test (overall a = .05) to determine which treatments differ from which other treatments. Also, compute the percentage of variance explained by the treatment effect (12). Conclude with an appropriate...
