STDEVA function

PRO BASIC

The STDEVA function in Jspreadsheet Formulas Pro is used to gauge the amount of variation or dispersion of a set of values. It calculates the standard deviation, considering both numbers and text or logical values in its calculation. This function is especially useful when your data set includes non-numerical values or when you want to evaluate the variability of your data based on a sample, not an entire population.

Documentation

Estimates the standard deviation of a sample dataset, including numbers, text representations of numbers, and logical values.

Syntax

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

Parameter	Description
`value1`	The first value in the sample. Can be a number, text, or logical value.
`valueN`	Optional. Additional values in the sample. Can be a number, text, or logical value.

Behavior

The STDEVA function calculates the standard deviation based on a sample, and unlike STDEV, it includes logical values and text representations of numbers in the calculation. The standard deviation is a measure of how much variance there is in a set of values. A low standard deviation means that most of the numbers are close to the average (mean). A high standard deviation means that the numbers are more spread out.

If the data set contains no data or only one data point, STDEVA returns the #DIV/0! error.
STDEVA includes the following data types in its calculation: logical values, text representation of numbers, and numbers.
Logical values and text representation of numbers are processed as follows: TRUE equals 1, FALSE equals 0. Text that cannot be translated into numbers causes the function to return the #VALUE! error.
Empty cells in the data set are ignored by STDEVA.

Common Errors

Error	Description
#DIV/0!	Occurs when the data set contains no data or only one data point.
#VALUE!	Occurs when the text in the data set cannot be translated into numbers.

Best practices

Always ensure that your data set has more than one data point to avoid the #DIV/0! error.

Be aware that STDEVA treats logical values and numerical text differently from other statistical functions, which may result in different results.

Avoid including non-numerical text in your data set to prevent the #VALUE! error.

Use STDEVA when you want to calculate the standard deviation of a sample that includes logical values and text representations of numbers. If you want to ignore these data types, consider using STDEV.P or STDEV.S instead.

Usage

A few examples using the STDEVA function.

// Numbers, text-numbers, and logical values
STDEVA(2, "3", TRUE, 8, FALSE)  
// Treats "3" as 3, TRUE as 1, FALSE as 0 → calculates standard deviation of [2,3,1,8,0]

// Range of cells
STDEVA(A1:A5)  
// Returns the estimated standard deviation of values in cells A1 through A5,
// including logicals and text that can be interpreted as numbers

// Mixed references
STDEVA(A1, B1, "5", TRUE)  
// Returns the standard deviation of cell values A1 and B1, plus the number 5 and TRUE (1)

// Invalid text
STDEVA(2, "hello", 4)  
// Returns #VALUE! because "hello" cannot be converted into a number
