Before Trying to Draw a Statistical Graph

• 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.
