Calculates standard deviation based on the entire population given as arguments. Ignores logical values and text.
A column that contains numbers corresponding to a population.
The standard deviation of the entire population.
STDEV.P assumes that the column refers to the entire population.
To compute the standard deviation with a sample of the population, use STDEV.S.
The STDEV.P function internally executes STDEVX.P, without any performance difference.
The following STDEV.P call:
STDEV.P ( table[column] )
corresponds to the following STDEVX.P call:
STDEVX.P ( table, table[column] )

DAX includes a few statistical aggregation functions, such as average, variance, and standard deviation. Other typical statistical calculations require you to write longer DAX expressions. Excel, from this point of view, has a much richer language. The Statistical Patterns are a collection of common statistical calculations: median, mode, moving average, percentile, and quartile. » Read more
