Below are four bivariate data sets and their scatter plots. (Note that all of the scatter plots are displayed with the same scale.) Each data sethis made up of sample values drawn from a population.

The same response may be the correct answer for more than one question. (a) For which data set is the sample correlation coefficient r closest to 0? X 5 the w, t data set (b) For which data set is the sample correlation coefficient r closest to 1? the x, y data set (c) Which data set indicates the strongest negative linear relationship between its two variables? the w, t data set (d) For which data set is the sample correlation coefficient r equal to - 1? the m, n data set Explanation Recheck 2025 McGrav Terms of Use | Privacy Center | | Accessibility 2 awww-awu.aleks.com C
