The following table was generated from the sample data of 10 junior high students
regarding the average number of hours they are unsupervised per night, the average
number of hours they play video games per night, and their final grades in their math
class. The dependent variable is the final grade, the first independent variable (x1) is
the number of hours unsupervised each night, and the second independent variable (x2)
is the number of hours of video games each night.
