TEXT is evaluated as zero, TRUE is evaluated as 1, and FALSE is evaluated as zero.
The STDEVA function is meant to estimate standard deviation in a sample.
If data represents an entire population, use the STDEVPA function.
STDEV.S replaces the older STDEV function, with the same behavior.
STDEVP Function
The STDEVP function calculates the standard deviation for data that represents a population.
STDEVP has been replaced with a newer function called STDEV.P, which has the same behavior.
STDEV.P Function
The Excel STDEV.P function calculates the standard deviation for a sample set of data.
STDEV.P calculates standard deviation using the “n” method, ignoring logical values and text.
