STDEVP Formula

STDEVP is the legacy version of STDEV.P, calculating the population standard deviation. It divides by n instead of n-1, giving the exact standard deviation when your data includes the entire population. Use STDEV.P in new spreadsheets for consistency, but STDEVP produces identical results.

Syntax

STDEVP(value1, [value2, ...])
ParameterDescription
value1 Parameter of the STDEVP function.
[value2 (Optional.) Parameter of the STDEVP function.
...] Parameter of the STDEVP function.

Examples

Population spread

Formula
=STDEVP(C2:C50)
Returns the population standard deviation for all 49 values. Identical to STDEV.P(C2:C50).

Team performance consistency

Formula
=STDEVP(B2:B12)
If B2:B12 contains every team member's performance metric, returns the exact spread. No need for sample correction since this is the whole team.

Multiple arguments

Formula
=STDEVP(10, 20, 30, 40, 50)
Returns 14.14 — the population standard deviation of these five values directly.

Common Errors

#DIV/0!

No numeric values provided.

#VALUE!

Non-numeric direct arguments.

Tips

Use STDEV.P instead

STDEVP is a compatibility function. STDEV.P is the preferred modern name but produces the same result.

Only for complete populations

Only use this when you have data for every member of the group. Sampling 100 employees out of 10,000 calls for STDEV.S, not STDEVP.

Relationship to variance

STDEVP is the square root of VARP. If you need variance instead, use VARP or VAR.P directly.
