"Statistics" is a general data analysis system to be used with the Radio Shack TRS-80® PC-2. The system consists of a Statistics program stored on cassette tape, a special keyboard overlay for your PC-2, and an instruction manual.

A few keystrokes allow you to perform data maintenance functions, calculate a wide variety of statistics on your data, display the analysis results on your PC-2, or list them on your PC-2 printer. The Statistics program and your data remain in the memory of your PC-2 even when the computer is turned off.

You can maintain your data file using these special program functions:
. Enter data.
. Add records to your data file.
. Delete records from your data file.
. Update values on any data record.
. Display records on your PC-2.
. List records on your PC-2 printer.
