question 5 of 10
what does it mean to say that a data point has a residual of 0?
a. the point lies above the regression line.
b. the predicted value for that point is 0.
c. the point falls at the origin.
d. the point lies directly on the regression line.

Explanation:

The residual of a data - point is calculated as the observed value minus the predicted value (residual = observed - predicted). If the residual is 0, it means the observed value is equal to the predicted value. In a regression context, this implies that the data - point lies directly on the regression line.

Answer:

D. The point lies directly on the regression line.
