Question 15

Determine whether the statement is true or false.If it is false,explain why or give an example that shows it is false.
​A linear regression model with a positive correlation will have a slope that is greater than 0.

Accepted Answer

A linear regression model with positive correlation means that as the independent variable increases, the dependent variable also increases. In this case, the slope of the line will be positive which implies that the slope is greater than zero. Therefore, the statement is true.
