The next step is to compute the Pearson r. Divide the covariance by the product of the two standard deviations. Note that the formula used to compute r is displayed in the formula bar. Using the Paste Functions. There are two paste functions that will calculate a Pearson r for you when given only the raw data. They are CORREL and PEARSON.

Calculate the Pearson r correlation between math and reading scores for this group of students. Convert the data to ranks, separately for each variable and calculate the Spearman rank-order correlation between math and reading score ranks for this group of students. Compare this value to the Pearson r calculated in part (a).
