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.

Each one of the questions below is either the: X,Y data set, U,V data set, W,T data set, or the M,N data set. Question three also has none of these data sets as an answer.

Solution

1). r closer to 1    : (m, n) data set

2). r equals to -1    : (u, v) data set

3). r closer to 0    : (w, t) data set

4). r strongest and negative    : (x, y) data set
