#### Abstract

Motivated by the sales prediction of ABCtronics, this paper aims to provide integrated process for creating a proper multiple linear regression model and detailed analysis of according parameters. With multiple independent variables, the linear regression model exams the relationship between a collection of data-overall market demand, price per chip and economic condition to the single dependent variable sales volume of ABCtronics. The target is set to be future prediction of sales volume with three observable variables. All outputs are statistical results from Minitab which contain regression equation, model summary with R 2 value and analysis of variance stating the significance level of each variable. With detailed output, a refined multiple regression model is then developed to get rid of the overall market demand term. Pure regression equation brings only numerical understanding, i.e., visualization is the next focus. Based on comparison and contrast, it is verified the accurateness of the refined model. These results shed light on the proper use of multiple linear regression on sale prediction model.
