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?

Answer 1

Answer: Option 'B' is correct.

Step-by-step 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 :

$R^2=1-\dfrac{SSE}{SST}\\\\0.75=1-\dfrac{11}{SST}\\\\0.25=\dfrac{11}{SST}\\\\SST=\dfrac{11}{0.25}\\\\SST=44$

Hence, SST for the data would be 44.

Therefore, Option 'B' is correct.

Answer 2

B 44
