Maths Apps ATAR - bivariate data: what is the coefficient of determination

Question

what is the coefficient of determination

Chelsey Louise · Accepted Answer

the accuracy at which we can predict one variable using the other
represented by r^2 (always between 0-1)
because if r=1 and the graph is perfectly linear we can predict variables with complete accuracy.
ie. given hight we can predict weight to r^2 %
