Question

A data set contains three points, and two of the residuals are -10 and 20.

Answer 1

If a data set contains three points, and two of the residuals are -10 and 20, the third residual is 10 (option B).

What is a residual?

A residual is the difference between the observed value and the estimated value of the quantity of interest.

The residual of a data points should normally sum up to zero (0). This means the following applies:

-10 + 20 + x = 0

x = 10

Therefore, if data set contains three points, and two of the residuals are -10 and 20, the third residual is 10.
