Graphing Single-Variable Statistical Data

kGraph 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.

Normal Distribution Curve (NDist)

The normal distribution curve is graphed using the following normal distribution function.
