What is the SST for the data set (1, 4), (2, 6), (4, 11) ? A. 9B. 16C. 26D. 11

SST stands for Sum - Squared Total, which is the Total of Sum of the

Squares.

This is the Sum of the Squares of the differences between the data and the mean of the set.

The mean of a data set is the sum of the values of each data divided by the number of data.

We have three data whose values are 4, 6 and 11.

Then, the mean of this data set is: [4 + 6 + 11] / 3 = 21/3 = 7

The squared differences are:

First dа ta: (4 - 7) ^2

Second dа ta: (6 - 7) ^2

Third dа ta: (11 - 7) ^2

Then the SST is = (4 - 7) ^2 + (6 - 7) ^2 + (11 - 7) ^2 = 9 + 1 + 16 = 26

Then, the answer is option C. 26
