Choose either: the x, y data set / the u, v data set / the w, t data set / the m, n data set / or none of the data sets for each figure attached

Below are four bivariate data sets and the scatter plot for each. (Note that each scatter plot is displayed on the same scale.) Each data set is made up of sample values drawn from a population.
