Question

If the coefficient of determination for a data set is 0.75 and the SSE for the data set is 11 what is the SST for the data set?

A 33
B 44
C 22
D 11

Answer 1

Answer: Option 'B' is correct.

Explanation:

Since we have given that

Coefficient of determination = 0.75

SSE for the data = 11

We need to find the SST for the data set.

As we know the formula :

`R^2=1-(SSE)/(SST)\\\\0.75=1-(11)/(SST)\\\\0.25=(11)/(SST)\\\\SST=(11)/(0.25)\\\\SST=44`

Hence, SST for the data would be 44.

Therefore, Option 'B' is correct.
