# STDEVA

## Definition

Calculates the standard deviation based on a sample, setting text to the value '0'.

#### Sample Usage

`STDEVA(1,2,3,4,5,6,7,8,9,10)`

`STDEVA(A2:A100)`

#### Syntax

`STDEVA(value1, [value2, ...])`

• `value1` - The first value or range of the sample.

• `value2, ...` - Additional values or ranges to include in the sample.

#### Notes

• Although `STDEVA` is specified as taking a maximum of 30 arguments, Excellentable supports an arbitrary number of arguments for this function.

• If the total number of values supplied as `value` arguments is not at least two, `STDEVA` will return the `#NUM!` error.

• `STDEVA` sets each text value encountered to `0` for the purpose of calculation. To return an error upon encountering text, use `STDEV`.

• `STDEVA` calculates standard deviation for a sample. To calculate standard deviation across an entire population, use `STDEVPA`.

• `STDEVA` is equivalent to the square root of the variance, or `SQRT(VARA(...))` using the same dataset.

`VARPA`: Calculates the variance based on an entire population, setting text to the value '0'.

`VARP`: Calculates the variance based on an entire population.

`VARA`: Calculates the variance based on a sample, setting text to the value '0'.

`VAR`: Calculates the variance based on a sample.

`STDEVPA`: Calculates the standard deviation based on an entire population, setting text to the value '0'.

`STDEVP`: Calculates the standard deviation based on an entire population.

`STDEV`: Calculates the standard deviation based on a sample.

`SKEW`: Calculates the skewness of a dataset, which describes the symmetry of that dataset about the mean.

`KURT`: Calculates the kurtosis of a dataset, which describes the shape, and in particular the "peakedness" of that dataset.

`DVARP`: Returns the variance of an entire population selected from a database table-like array or range using a SQL-like query.

`DVAR`: Returns the variance of a population sample selected from a database table-like array or range using a SQL-like query.

`DSTDEVP`: Returns the standard deviation of an entire population selected from a database table-like array or range using a SQL-like query.

`DSTDEV`: Returns the standard deviation of a population sample selected from a database table-like array or range using a SQL-like query.

`DEVSQ`: Calculates the sum of squares of deviations based on a sample.

`AVEDEV`: Calculates the average of the magnitudes of deviations of data from a dataset's mean.
