Statistics Exercises - Solutions Covariance, correlation, the t-test 1. Consider the following data: x y 0 4 2 3 4 1 5 1 7 2 8 1 10 0 Calculate the correlation coefficient between variables x and y. First we calculate the means E(x) = 5.14 and E(y) = 1.71. Then, we calculate the unbiased estimators for the variance V ar(x) = 12.14 and V ar(y) = 1.90. Using the formula for the unbiased estimator for the covariance, we get Cov(x, y) = −4.12. Our correlation coefficient then is Corr(x, y) = −0.86.
