Why do correlation coefficients greater than 0.50 rarely occur in the social sciences?

When working with two nominal variables, each with two levels, a chi-square test for goodness of fit would be the appropriate test to use.

Your statistics professor was interested in the extent to which class attendance predicted test performance (% test score) in Introductory Psychology. An analysis of the data revealed the following information:N = 127; rxy = .518Mx = 17.43; SDx = 4.21; SSx = 2248My = 71.46; SDy = 12.82; SSy = 20888The formula for the regression line was calculated as = 43.941 + 1.579X. Using this information calculate the adjusted r2.

When the within-groups variance is much larger than the between-groups variance, we infer that the sample means are _____ one another, and we _____ the null hypothesis.
