What term is used to describe the shape of a distribution in which the scores pile up on the left-hand side of the graph and taper off to the right?

Which of the following sets of sample data would produce the smallest value for an independent-measures t statistic?

Under what circumstances is a score that is 5 points above the mean considered a central value–meaning it is relatively close to the mean?

An analysis of variances produces dftotal = 29 and dfwithin = 27.  For this analysis, what is dfbetween?

A population of scores has µ = 44.  In this population, a score of X = 40 corresponds to z = –0.50.  What is the population standard deviation?

What is the critical value for a correlation with n=20, one-tailed, and an alpha level of 0.05?

A set of n = 10 pairs of scores has ΣX = 20, ΣY = 30, and ΣXY = 74.  What is the value of SP for these data?

A set of n = 40 pairs of scores (X and Yvalues) produces a regression equation of Ŷ = 13X + 15. Find the predicted Y value for an X score of 3.
