The following data has been collected for two variables, X and Y.
A simple linear regression model has been constructed using the data in the table and is being used to predict values for the variably Y
Of 3, 7, 18 and 35, how do I determine which for variable X would lead to an interpolated or extrapolated value for variable Y?
Please see the attached Word document
Interpolated values for the variable Y occur when the value of the X variable is within the range of the X values used to create the prediction model. In this case ...
This solution explains the meaning of interpolation and extrapolation when using a linear regression model for predicting Y (the response variable) at a given value of X (the explanatory variable).
