2. Calculating and Graphing Single-Variable 
Statistical Data
Single-variable data is data with only a single variable. If you are calculating the average height 
of the members of a class for example, there is only one variable (height).
Single-variable statistics include distribution and sum. The following types of graphs are 
available for single-variable statistics.
You can also use the procedures under “Changing Graph Parameters” on page 6-1 to make 
the settings you want before drawing each graph.
Normal Probability Plot

XList specifies the list where data is input, and Mark Type is used to select from among the

Pie Graph
You can draw a pie graph based on the data in a specific list. The maximum number of graph 
data items (list lines) is 20. The graph is labeled A, B, C, and so on, corresponding to lines 1,
2, 3, and so on of the list used for the graph data.
When “%” is selected for the “Display” setting on the general graph settings screen (page 6-3), 
a value showing the percentage is displayed for each of the alphabetic label letters.
Histogram
XList specifies the list where the data is input, while Freq specifies the list where the data 
frequency is input. 1 is specified for Freq when frequency is not specified.
