Complete a multiple regression using the data “Use Sales” as the Y Range and “Social Media,” “Web” and “Print” as the X-Range.

Unit 2 assignment – marketing regression

The formula for a multiple regression is: Y = β0 + β1X1 + β2X2 + β3X3

Where Y represents the dependent variable (Sales), then X1 means Social Media, Web and Print.

To calculate the coefficients (β) of each independent variable, we need to use least squares estimation. These are the results:
Y= 4500+50*Social Media + 200*Web – 100 *Print
