affect the value of the correlation?
At the beginning of this chapter we discussed a study
by Judge and Cable (2010) demonstrating a posi-
tive relationship between weight and income for
a group of men. The following are data similar to
those obtained in the study. To simplify the weight
variable, the men are classified into five categories
that measure actual weight relative to height, from
1 = thinnest to 5 = heaviest. Income is recorded as
thousands earned annually.
a. Calculate the Pearson correlation for these data.
b. Is the correlation statistically significant? Use a
two-tailed test with a = .05.
