A researcher reports an F-ratio with df = 2, 18 from an independent-measures research study.  Based on the df values, how many treatments were compared in the study and what was the total number of subjects participating in the study?

What is the critical value for a repeated measures ANOVA with N=46, 5 levels for factor A, dfWG = 86, and an alpha level of 0.01?

The values in the following matrix are treatment means from a two-factor study. One of the means is missing. What value for the missing mean would most likely result in no main effect for factor A, factor B, and no interaction?     B1 B2 A1 13 16 A2 16 ?

Two samples from the same population both have n = 10 scores with M = 45.  If the t statistic is computed for each sample, then what is the relationship between the two t values?

A distribution with µ = 55 and σ = 6 is being standardized so that the new mean and standard deviation will be µ = 50 and σ = 10.  When the distribution is standardized, what value will be obtained for a score of X = 58 from the original distribution?

What term is used to identify the mean of the distribution of sample means?

An independent-measures research study uses two samples, each with n = 12 participants.  If the data produce a t statistic of t = 2.50, then which of the following is the correct decision for a two-tailed hypothesis test?
