STDEVA Formula Syntax

=STDEVA(A1:A5)

Example Use Case

Estimating sample standard deviation including text and logical values

Understanding the STDEVA Formula

The STDEVA function in Excel calculates the sample standard deviation, treating text as 0 and logical values (TRUE/FALSE) as 1/0. It’s a broader version of STDEV, useful for mixed datasets—like survey responses with flags.

STDEVA(A1:A5) with 10, 'text', TRUE, , 20 returns ~8.66, counting text as 0 and TRUE as 1 in the sample formula. It’s inclusive, making it ideal when non-numeric data impacts variability.

Why Use STDEVA?

STDEVA captures all—think mixed data analysis or quality checks with text entries. Its sample-based (n-1) approach adjusts for small sets, offering a fuller picture of spread in diverse data.
