problem 9 presented data showing a positive relationship between weight and income for a sample of professional men. however weight was coded in five categories that 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. convert the weights and the incomes into ranks and compute the spearman correlation for the scores in problem 9.

Weight (x) : 4 5 3 2 1 3 1 5

Income (y) : 151, 88, 52, 73, 49, 92, 56, 143
