True Slope
Definition
The true slope refers to the actual value representing the change in the response variable for each unit increase in the explanatory variable in a linear regression model. It is the population parameter that we aim to estimate.
Analogy
Imagine you are driving on a straight road and your speedometer shows how much your speed changes for every mile you drive. The true slope would be the actual change in speed per mile, regardless of what your speedometer displays.
