Q. 11 - Elementary Statistics

Question

11. Using a regression equation to make predictions for values of the predictor variable outside the range of the observed values of the predictor variable is called ________

Step-by-Step Solution

Answer

Using a regression equation to make predictions for values of the predictor variable outside the range of the observed values of the predictor variable is called extrapolation.

Step 1: Concept Introduction

Extrapolation:

Extrapolation is when the projected value of $y$ for a given value of predictor variable $x$ lies outside the range of $x$.

Step 2: Explanation

Extrapolation is a technique for determining the value of a predictor variable outside of the range of observed values.

Extrapolation is the process of utilizing a regression equation to produce predictions for values of the predictor variable that are outside the range of the observed values of the predictor variable.
