CASE: You want to determine the degree/strength of relationship between height and weight. Variable X is the heightwhile variable Y is the weight.Question 2. If height increases and weight declines, the computed r is r= -0.65. What is the relationship between the 2variables? How strong is the relationship? Plot it below using the scatterplot.
