Suppose you and a friend each take different random samples of data pairs (x,y) from the same population. Assume the samples are the same size. Based on your samples, you compute r = 0.83. Based on her sample your friend computes 0.79. Is your friendâ€™s value for r wrong? Explain

No. Different samples, from the same population may result in different value for sample statistic r.
