Question

Some residuals for a scatterplot are given. For x = 3, the residual is –5. For x = 5, the residual is –1. For x = 7, the residual is 3. For x = 9, the residual is 0. For which value of x is the data point farthest from the line of best fit?

Answer 1

x = 3

Explanation:

Residuals are the difference between a predicted value, found by a line of best fit, and the actual value. This means the larger the residual, the farther the data point is from the line of best fit.

The largest residual listed is for x = 3, which is -5. This means this point is the farthest away from the line of best fit.

Answer 2
