Statistical Calculations (SD/REG)

kStatistical Calculation Sample Data

A Inputting Sample Data

You can input sample data either with statistical frequency turned on (FreqOn) or off (FreqOff). The calculator’s initial default setting is FreqOn. You can select the input method you want to use with the setup screen statistical frequency setting (page 9).

A Maximum Number of Input Data Items

The maximum number of data items you can input depends on whether frequency is on (FreqOn) or off (FreqOff).

	Frequency Setting	FreqOn	FreqOff
Calculation Mode
SD Mode		40 items	80 items
REG Mode		26 items	40 items

A Sample Data Clear

All sample data currently in memory is cleared whenever you change to another calculation mode and when you change the statistical frequency setting.

kPerforming Single-variable Statistical Calculations

To perform the example operations in this section, first select SD (N4) as the calculation mode.

A Inputting Sample Data

Frequency On (FreqOn)

The following shows the key operations required when inputting class values x1, x2, ...xn, and frequencies Freq1, Freq2, ... Freqn.

{x1}1,(;) {Freq1}m(DT) {x2}1,(;) {Freq2}m(DT){xn}1,(;) {Freqn}m(DT)

Note

If the frequency of a class value is only one, you can input it by pressing {xn}m(DT) only (without specifying the frequency).
