8.4 Statistical Operations.
Statistical operations in KeyPlus, allow you to enter a set of numbers, and KeyPlus then calculates
their mean (average), median, mode, standard deviation, minimum, maximum, etc. You can review
the statistical results, insert them into documents, or use them in calculations, etc. You can also
review the data in the order you entered it, in numeric order or as a frequency table. The data set can
be edited to correct mistakes and can be saved in a file for later use, to share, or export for use in a
database or spreadsheet. You can paste in a set of numbers copied from a document, as well as
being able to import data from databases and spreadsheets.

Menu/Statistical Functions Review List. The Data Set Menu is where data sets are reviewed, saved,
loaded and cleared. It also provides you with the option to turn Data Entry on or off and to paste
data from the clipboard into the data set. The Statistical Functions Menu/Statistical Functions
Review List is for performing numerous statistical operations, such as finding the mean and the sum
