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?

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?

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?

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

If an analysis of variance is used for the following data, what would be the effect of changing the value of M2 to 20?Sample DataM1 = 10    M2 = 15SS1 = 90    SS2 = 70

What is the value of Σ(X – 2) for the following scores?  Scores: 2, 3, 5

If other factors are held constant, how does sample size influence the likelihood of rejecting the null hypothesis and measures of effect size such as r2 and Cohen’s d?

Which combination of factors is most likely to produce a significant value for an independent-measures t statistic?
