Problem 12 presented data showing a negative relationship between weight and income for a sample of working women. However, weight was coded in five categories, which could be viewed as an ordinal scale rather than an interval or ratio scale. If so, a Spearman correlation is more appropriate than a Pearson correlation.
a. Convert the weights and the incomes into ranks and compute the Spearman correlation for the scores in problem 12.
b. Is the Spearman correlation large enough to be significant?
