For this section, we’ll be using the spreadsheet from the last section after working through the example so that we can compare the two methods. In this case the p-value is less than 0.05, which indicates that the explanatory variables hours studied and prep exams taken combined have a statistically significant association with exam score. To make it simple and easy to understand, the analysis is referred to a hypothetical case study which provides a set of data representing the variables to be used in the regression model.

To do this, you would set up three columns of data: X, X 2, and Y. Hence as a rule, it is prudent to always look at the scatter plots of (Y, X i), i= 1, 2,…,k.If any plot suggests non linearity, one may use a suitable transformation to attain linearity.

This is the average distance that the observed values fall from the regression line. Step 2: Perform multiple linear regression. As we can see here, the p-value in anova table is less than 0.0001 which is good. For example, a student who studies for three hours and takes one prep exam is expected to receive a score of 83.75: exam score = 67.67 + 5.56*(3) – 0.60*(1) = 83.75.

Keep in mind that because prep exams taken was not statistically significant (p = 0.52), we may decide to remove it because it doesn’t add any improvement to the overall model. Suppose we want to know if the number of hours spent studying and the number of prep exams taken affects the score that a student receives on a certain college entrance exam.
