Use the correlation coefficient to find the coefficient of determination. What percent of variation in the response variable can be explained by changes in the explanatory variable? r=−0.5 coefficient of determination: 0.1; 10% of the variation in the response variable can be explained by changes in the explanatory variable coefficient of determination: 0.25; 25% of the variation in the response variable can be explained by changes in the explanatory variable coefficient of determination: 0.5; 50% of the variation in the response variable can be explained by changes in the explanatory variable coefficient of determination: 0.71; 71% of the variation in the response variable can be explained by changes in the explanatory variable

Vocaloid:

coefficient of determination is r^2 (not just r, so be sure to square your r-value) it gives you the % of variation in the response variable which can be explained by changes in the explanatory vairable
