8.4.5.1 Reviewing the Statistical Functions.
At any time while you are entering data or once you have finished, you can review the results of the
statistical functions by pressing READ with S. What happens next depends on whether or not Data
Entry is on.
When Data Entry is on, the Statistical Functions Review List is displayed and you can review the
statistical results an item at a time by pressing SPACE repeatedly, or jump directly to a particular
result by pressing its hot key.
When Data Entry is off, the Statistical Functions Menu is displayed. This allows you to review the
statistical results by pressing SPACE repeatedly, as well as to select any result for use in a
calculation. To select any result for use in a calculation, either press ENTER when the result is
displayed or enter the menu and press the hot key. For example, to calculate the mean plus 2 times
the standard deviation, follow these steps:
1. In the calculator ensure Data Entry is off and the calculator is cleared.
2. To enter the mean, select the Statistical Functions Menu by pressing READ with S. You can
then either move along to “Mean” and press ENTER or just press the hot key for mean, which
is M. You will be returned to the calculator with the mean inserted into your calculation.
3. Enter “plus 2 times” and insert the standard deviation by selecting the “Sample standard
deviation” from the Statistical Functions Menu again. You will once again be returned to the
calculator and the sample standard deviation will now be inserted into your calculation.
4. Finally press ENTER to obtain the result.
To use a statistical result in another KeySoft application, use the clipboard. Simply review the result
in the Statistical Functions Review List or the Statistical Functions Menu and copy the value to the
clipboard by pressing CONTROL with C. Insert the result and paste the clipboard into the Word
Processor, via the Block Commands Menu. Otherwise, move to the application in which you want
to insert the result and paste the clipboard by pressing CONTROL with V.
8.4.6 Reviewing the Data Set.
It is often easy to accidentally enter the wrong items or add data that is already in the data set. Also,
you will often want to review your data using a method that differs from how the data was entered.
KeyPlus offers three different ways to review your data:
1. The order you entered the data.
2. The frequency order.
3. The numeric order.
