The form lists the data in ΣDAT, shows that column 1 is selected (there is only one column in the current ΣDAT). Move about the form with the arrow keys, and press the @CHK@ soft menu key to select those measures (Mean, Standard Deviation, Variance, Total number of data points, Maximum and Minimum values) that you want as output of this program. When ready, press @@@OK@@. The selected values will be listed, appropriately labeled, in the screen of your calculator. For example:

Sample vs. population

The pre-programmed functions for single-variable statistics used above can be applied to a finite population by selecting the Type: Population in the SINGLE-VARIABLE STATISTICS screen. The main difference is in the values of the variance and standard deviation which are calculated using n in the denominator of the variance, rather than (n-1). For the example above, use now the @CHOOS soft menu key to select population as Type: and re-calculate measures:
