Statistical Graphs

k Configuring the Frequency Setting

The frequency is a value that specifies how many times each of the statistical data items is

repeated. A value of 1 is the initial default for this setting. With this setting, each data item (x)

or data pair (x, y) is represented as one point on the graph.

In cases where there is a large amount of data, however, plotting one point per data item (x)

or data pair (x, y) can cause the graph to become cluttered and difficult to read. If this

happens, you can specify a frequency value for each data item, which will reduce the

number of plots of very frequent data items and make the graph easier to read.

u To specify the frequency of each data item

1. Input the frequency values on the spreadsheet.

•For this example, input the frequency values for

the example data on page 9-6-3.

Frequency column (C)

2. Press 6 (SET) on the GRPH submenu to display the graph settings screen.

3. Use the f and c cursor keys to move the highlighting to Frequency.

4. Press 2 (CELL).

•This enables cell range input for the Frequency setting. The function menu will

change to the colon (:).

5. Input the range of the cells that specify the frequencies (C1:C5 in this example).

•To input the colon (:), press 1(:).

6. After the setting is the way you want, press J.
