 We will demonstrate SLR with some SOCR built-in examples. The first example (EXAMPLE 1) is based on the data taken from "An Introduction to Computational Statistics: Regression Analyses" by Robert Jennrich, Prentice Hall, 1995 (Page 4). The data describe exam and home scores of a class of students, where '''M''' stands for midterm, '''F''' for final, and '''H''' for homework.

-* Use column '''M''' as the regressor (that is, 'x', the independent variable) and column '''F''' as the response (that is, 'y', the dependent variable). So you can simply ignore the column '''H''' for this activity. To tell the computer which variables are assigned to be the regressor and response, we have to do a "Mapping." This is done by clicking on the "'''Mapping'''" button first to get to the Mapping Panel, and then map the variables. For this Simple Linear Regression activity, there are two places the variables can be mapped to. The top part says '''DEPENDENT''' that you'll need to '''map''' the dependent variable you want here. Just click on '''ADD''' under '''DEPENDENT''' and that will do it. If you change your mind, you can click on '''REMOVE'''. Similar for the '''INDEPENDENT''' variable. Once you get the screen to look like the screenshot below, you're done with the '''Mapping''' step. (Note that, since the columns C3 through C10 do not have data and they are not used, just ignore them.)
