Question

the scattered diagram and the regression line characterize the relationship between the gpa and the independent variable hours per week studied. the residual errors are defined as

a. the vertical distance from the data points to the regression line

b. the vertical distance from the data points to the horizontal axis

c. the horizontal distance from the data points to the veritical axis

d.shortest distance from the data points to the regression line.

Explanation / Answer

a) is the right answer

the vertical distance from the data points to the regression line

regression line showing exact relationship

above it show the positive residual error because value of gpa is greater than expected and

difference between gpa value and expected value is showing error which is vertical distance difference

down it will show negative residual error
