Consider again the two variables described in Exercise 18.39, test grade and speed in taking the test. Imagine that each of the following numbers represents the Spearman correlation coefficient that quantifies the relation between these two variables-test grade converted to ranks such that the top grade of 98 is ranked 1, and speed in taking the test with the fastest person ranked 1. What does each coefficient suggest about the relation between the variables? Using the guidelines for the Pearson correlation coefficient, indicate whether each coefficient is roughly small (0.10), medium (0.30), or large (0.50). Specify which of these coefficients suggests the strongest relation between the two variables as well as which coefficient suggests the weakest relation between the two variables. [You calculated the actual correlation between these variables in Exercise 18.39(b).]
