# Math Help - correlation

1. ## correlation

given that the correlation coefficient for heights and weights of ten players was r = 0.8261,

how do we determine what percentage of the variation in weights was explained by heights of players and what percentage of the variation in heights was explained by weights of players?

thanks

2. The answer is obtained by simply squaring $r$ , $r^2 = 0.8261^2 = \cdots$
