Question

if the observed value is 69.4 and the predicted value is 70.4, what is the residual value? round your answer to the nearest hundredth.

Answer 1

The residual value will be equal to -1.

What is residual value?

A residual is a difference between the observed y-value of a data point and the predicted y-value on a regression line for the x-coordinate of the data point. A residual is positive when the point is above the line, negative when it is below the line, and zero when the observed y-value equals the predicted y-value.

Take, for instance, we have the following data entry:

Observed value = 69.4

Predicted value = 70.4

The residual (r) would be:

Residual value = 69.4 - 70.4 = -1

Therefore the residual value will be -1
