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.
