Question

Find the residual if you know the actual number is 3 and the predicted value is 1.6

A. 1.4
B. 2.2
C. 0.4
D. There is no correct answer given
E. -0.5

Answer 1

The correct option is A.

Explanation:

The difference between actual value and predicted value is called residual.

Formula of residual is

`e=y-\hat{y}`

Where, y is observed value or actual value and
`\hat{y}` is predicted value.

`e=3-1.6`

`e=1.4`

The value of residual is 1.4 and option A is correct.
