Question

A line of best fit predicts that when x equals 29, y will equal 32.75, but y actually equals 32. What is the residual in this case

Answer 1

The residual is 0.75

Explanation:

Recall that the residual is the VERTICAL distance between the y-value of the data point and the y-value of the predicted line. This distance can be calculated using the absolute value of the difference between these y-values.

Therefore, in our case the residual is: |32 - 32.75| = |-0.75| = 0.75
