Activity Overview

In this activity, students use the statistical features of the calculator to calculate statistical results, perform regressional analyses, and graphically display statistical data.

Before the Activity

  • Set up the calculator as explained in the activity
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 121 - 146 from the attached activity PDF file for the class
  • During the Activity

    Distribute the pages to the class.

    Follow the Activity procedures:

  • Enter listed data into the calculator directly from the home screen, or by using the list editor
  • Plot a histogram for the entered data
  • Compute the summary statistics for one variable data
  • Edit lists using the List Editor
  • Use the sum command to compute summary statistics


  • Enter two-variable statistical data, and graph a scatter plot and an xyLine plot
  • Compute the summary statistics for two variable data
  • Understand how to recall summary statistics
  • Sort the data in ascending order
  • Find the Least Squares Regression line for the data, and determine its equation
  • Store the line in the graphing editor


  • Predict a y-value for a given x-value (and vice versa) using the regression curve
  • Use the Forecast option to compute the predicted value


  • Study various regression models which can be performed by the calculator
  • Perform a Power regression on a bivariate data
  • Graph the scatter diagram, the linear regression curve, and the power regression curve in the same viewing window
  • Compare the two regression curves
  • Using the Sum command, compute the values for the sum of the squares of the differences
  • Select the best regression model based on the SSD values


  • Determine the correlation between the data
  • Examine the Cumulative Distribution Programs
  • After the Activity

    Students complete the exercises on the Activity sheet.

    Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
