Estimates variance based on a sample. In addition to numbers, text and logical values such as TRUE and FALSE are included in the calculation. Syntax VARA ( value1 , value2 , ... ) Value1,value2,... are 1 to 30 value arguments corresponding to a sample of a population. Remarks VARA assumes that its arguments are a sample of the population.
