Which one(s) of the following are true about the statistic called "r-squared" (r2). Check all that apply (two answers are correct). It can be negative. r-squared for a simple linear regression will always be the square of the correlation. It is a measure of the percentage of the variability in the explanatory variable explained by a regression line. It is a measure of the percentage of the variability in the response variable explained by a regression line.
