Starting a New Statistics Problem

When you start a new statistics problem that does not use any previously entered data values, being by clearing the statistics registers and selecting 1- or 2- variable statistics. Clearing the statistics registers does not affect any values stored in the calculator's data register memories. However, the t-register is cleared.

The Number of Variables

In 1-variable statistics, a data value is represented as xn, where n = 1, 2, ..., N. (N is the total number of data values).

In 2-variable statistics, a data value is represented as (xn,yn). The x value is the independent variable, and the y value is the dependent variable.

Clearing the Registers

To clear the statistics registers and select 1- or 2- variable statistics, use the following procedure.
  1. Press [ STAT ] to display the STAT FUNCTIONS function.
  2. Press { CLR }. The following menu is then displayed.
    D_pxpLSS
    { CS1 } - 1-variable statistics
    { CS2 } - 2-variable statistics
  3. Select either 1- or 2- variable statistics.

After you press { CS1 } or { CS2 }, the STAT FUNCTIONS menu is displayed.
