Below are four bivariate data sets and their scatter plots. (Note that al of the scatter plots are displayed with the same scale.) Each data set i made up of sample values drawn from a population. Answer the following questions about the relationships between pairs variables and the values of r, the sample correlation coefficient. The same response may be the correct answer for more than one question (a) For which data set is the sample correlation coefficient r equal to 1 ? (b) Which data set indicates the strongest positive linear relationship between its two variables? (c) For which data set is the sample correlation coefficient r closest to 0 ? (d) For which data set is the sample correlation coefficient r closest to ?1 ?
