In MS-Excel 2007, STDEV(number1, number 2, ... ) is a statistical function that

estimates standard deviation based on a sample by ignoring logical values and text in the sample

estimates standard deviation based on a sample by including logical values and text in the sample

calculates standard deviation based on entire population by ignoring logical values and text

calculates standard deviation based on entire population by including logical values and text

Explanation

In MS-Excel 2007, the STDEV function is used to estimate the standard deviation based on a sample of a population. It is one of the most commonly used statistical functions for data analysis. Key characteristics include:

Sample Basis: It assumes that its arguments are a sample of the population. If the data represents the entire population, the STDEVP function should be used.
Exclusion: It ignores logical values (TRUE/FALSE) and text that appear in arrays or cell references.
Calculation: It uses the "n-1" method (Bessel's correction) to calculate the square root of the variance.

If you need to include logical values and text in the calculation (treating TRUE as 1 and FALSE/text as 0), you would use the STDEVA function instead.
