Using your completed table, you can calculate the Spearman correlation in two different ways. One way is to use the Pearson correlation formula on the ranks of the data. When you do this, you get rs - -0.62. The second way to calculate the Spearman correlation is to use the following formula: Is = 1 - 62D2 n(n2 - 1) In this formula, D represents the difference between ranks for each individual. Using this formula, you get rs - -0.51....
