Question

Consider the paired dataset x = {0.78, 1.96, 1.02, 0.91} and y = {5.66, 3.18, 4.89,...

Consider the paired dataset x = {0.78, 1.96, 1.02, 0.91} and y = {5.66, 3.18, 4.89, 2.45}. Compute the sample correlation coefficient r(x, y) for the dataset by hand. If you just write the answer obtained by using a software, you will get 0. You can however use calculator for intermediate computations, such as finding x or sy.
