A common concern for students (and teachers) is the assignment of grades for essays or term papers. Because there are no absolut
e right or wrong answers, these grades must be based on a judgment of quality. To demonstrate that these judgments actually are reliable, an English instructor asked a colleague to rank-order a set if term papers. The ranks and the instructor's grades for these papers are as follows:
Rank: 1, 2, 3, 4, 5, 6,7,8,9,10, 11
Grade: A,B, A, B, B, C,D, C,C,D, E
A) Compute the Spearman correlation for these data.
B) Is there a significant correlation between the two instructors' judgments of the papers. Use a two tailed test with alpha = 0.05
