Step 2: Enter the data Column A: input values Column B: output values For this example, I used the data from the Building and Combining functions task. Column A represents number of years since 2000; column B represents the crime rate for City A.
Step 3: Graph the Data 1. Go to: Tools, Graph, Scatterplot 2. Designate the input values (horizontal) and output values (vertical) For this example, Column A, number of years since 2000, is my input/horizontal and Column B, crime rate for City A, is my output/vertical
Step 4: Draw Regression Models 1. Go to: Options, Draw Regression Model 2. There you have it, the equation for the line of best fit!
