6-2-1 Calculating and Graphing Single-Variable Statistical Data 6-2 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 6-1-2 to make the settings you want before drawing each graph. k Normal Probability Plot (NPP) This plot compares the data accumulated ratio with a normal distribution accumulated ratio. XList specifies the list where data is input, and Mark Type is used to select from among the marks you want to plot. Press A, J or !J(QUIT) to return to the statistical data list. k Histogram (Bar Graph) (Hist) 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. ⇒ w(Draw) The display screen appears as shown above before the graph is drawn. At this point, you can change the Start and Width values. 20050401
