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
