Example
Assume you have installed a temperature sensor in Cupertino, California. The sensor records each
day’s high and low temperatures. In addition, you have kept a record of each day you turned on the
air conditioner in your condo. The data from the first few days is shown in the following table and is
used as a sample for the population of high and low temperatures (note that this is an example only;
this would not be statistically valid).
=VARA(B2:B13) returns 616.3864, the dispersion as measured by VARA, of the sample of daily high
temperatures.
