7-8 Test, Confidence Interval, and Distribution
Calculations
Test, confidence interval, and distribution calculations are all performed using the ClassPad’s
Program application. The following is a general overview of the steps that are involved.
1. Use statistical commands to build the necessary expressions and write them into the
program.
2. Write the “DispStat” command into the program.
• The “DispStat” is a command for displaying statistical calculation results. Statistical
calculation results cannot be displayed unless the program includes a “DispStat”
command.
3. Save the program.
4. Run the program.
