Question

If the coefficient of determination for a data set is 0.75 and the SSE for the data set is 13, what is the SST for the data set?

Answer 1

Answer : SSE = 9
r^2 = 0.75
r^2 = 1 - (SSE/SST)
SSE/SST = 1 - r^2 = 1 - 0.75 = 0.25
SST = 9/0.25 = 36

Answer 2

The SST for the data set is 52 (APEX VERIFIED)
