Graphing Single-Variable Statistical Data
I
Graph Parameter Settings (page 7-3-3, 7-3-4)
• [XList] specifies the list that contains the data to be plotted.
• [Freq] specifies the frequency of the data.
• If [Show Outliers] box is checked, “outlier” square symbols are shown instead of “whisker”
lines where a data value is relatively large or small compared to the other data values.
Tip
• When specifying a list of frequency values, make sure that the list contains positive integers only.
Non-integer values (such as those with a decimal part) cause an error during statistical
calculations.
