As the reader can see, height and weight are strongly but not perfectly related to one another. Tall persons tend to weigh more, short persons less, but there are some exceptions. If we were to compute the correlation coefficient between height and weight-a simple statistical task out lined in the following=we would value of about +.80, indicating a strong, positive relationship between these measures
