Question

True or False?

1. The scatter plot is a two dimensional graph that is used to graphically represent the relationship between two quantitative variables.

2. Both a scatter plot and the correlation coefficient can distinguish between a curvilinear and a linear relationship.

Given this, we know that approximately 57 percent of the variation in the y variable is explained by the x variable
