Q. 4.84

Question

A measure of the total variation in the observed values of the response variable is the------.

The mathematical abbreviation for it is----.

Step-by-Step Solution

Verified

Answer

A measure of the total variation in the observed values of the response variable is the total sum of square

The mathematical abbreviation for it is SST

1Step 1: Given Information

To determine the blank in the given statement.

2Step 2: Explanation

The total square sum is:

The total sum of squares is a measure of the total deviation in the observed values of the response variable explained by the regression. The total sum of squares formula is as follows:

$S S T = \sum {(y_{i} - \bar{y})}^{2}$

As a result, the total sum of squares is a measure of the total variation in the observed values of the response variable. SST is the mathematical shorthand for it.
