A Inputting Sample Data

Frequency On (FreqOn)

The following shows the key operations required when inputting class values (x1, y1), (x2, y2), ...(xn, yn), and frequencies Freq1, Freq2, ... Freqn.

{x1},{y1}1,(;) {Freq1} m(DT) {x2},{y2}1,(;) {Freq2} m(DT){xn},{yn}1,(;) {Freqn} m(DT)

Note

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

Frequency Off (FreqOff)

In this case, input each individual data item as shown below. {x1},{y1} m(DT){x2},{y2} m(DT){xn},{yn} m(DT)

A Viewing Current Sample Data

After inputting sample data, you can press c to scroll through the data in the sequence you input it. The $ symbol indicates there is data below the sample that is currently on the display. The ` symbol indicates there is data above.

When the statistical frequency setting is FreqOn, data is displayed in the sequence: x1, y1,

Freq1, x2, y2, Freq2, and so on. In the case of FreqOff, it is displayed in the sequence: x1, y1, x2, y2, x3, y3, and so on. You can also use f to scroll in the reverse direction.

A Editing a Data Sample

To edit a data sample, recall it, input the new value(s), and then press E.

A Deleting a Data Sample

To delete a data sample, recall it and then press 1m(CL).

A Deleting All Sample Data

See “Deleting All Sample Data” (page 41).

A Statistical Calculations Using Input Sample Data

To perform a statistical calculation, input the applicable command and then press E. To

determine the mean (oor p) value of the current sample data, for example, perform the operation shown below.
