Graphing Paired-Variable Statistical Data

Drawing a Regression Graph

Use the procedures below to input paired-variable statistical data. Next perform regression

using the data and then graph the results. Note that you can draw a regression graph without

performing the regression calculation.

Example 1: Input the paired-variable data shown below and plot the data on a scatter

diagram. Next, perform logarithmic regression on the data to display the

regression parameters, and then draw the regression graph.

list1 = 0.5, 1.2, 2.4, 4.0, 5.2

list2 = –2.1, 0.3, 1.5, 2.0, 2.4
