Question

In a simple linear regression model, the slope term is the change in the mean value of y associated with _____________ in x.

A) a variable change
B) a corresponding increase
C) a one-unit increase
D) no change

Answer 1

a one-unit increase

Explanation:

In a simple regression model, the relationship between x and y can be represented by the equation y = ax+b, where

• a is the slope

• b is the y-intercept

The slope term is the change in the mean value of y associated with a one-unit increase in x.
