Question

When we use a least-squares line to predict y values for x values beyond the range of x values found in the data, are we extrapolating or interpolating? are there any concerns about such predictions?.

Answer 1

Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.

Given that,

We have to find are we extrapolating or interpolating when we use a least-squares line to forecast y values for x values outside the range of x values seen in the data.

Option A) We are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.

What is extrapolation?

Extrapolation is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable.

Therefore, Option A is correct that is we are extrapolating. Because the pattern of the data may vary outside the x range, extrapolation is risky.
