Before Trying to Draw a Statistical Graph

uFreq

Tap the down arrow button, and then select the frequency setting from the list that appears.

To do this:

Select this option:

Plot each data value once

1

Specify a list whose values indicate the frequency of each

list1 — list6

(or a list name you

data value

assigned)

 

 

 

•The initial default frequency setting is 1. Specifying a list that causes each data value to be plotted five times helps to improve the appearance of scatter plots.

•A list of frequency values can contain non-zero integers and decimal values. In the case of a MedBox, ModBox, or MedMed graph, however, a frequency list can contain positive integers only. Non-integer values (such as those with a decimal part) cause an error during statistical calculations.

uMark

Tap the down arrow button, and select the shape you want to use for the plot points of a scatter diagram (Scatter), xy line graph (xyLine), or normal probability plot (NPPlot).

Tip

• The default graph setting for all nine StatGraph setups is a scatter plot (Scatter).
