DEVSQ function

PRO

The DEVSQ function in Jspreadsheet Formulas Pro is a tool that helps you measure the variability within a set of data. It works by calculating the total of the squared differences between each data point and the average of all data points. This is useful in statistics as it can provide insight into how spread out your data is around the average. This function is often used in various scientific and financial calculations.

Documentation

Calculates the sum of squares of deviations from the mean of a dataset.

Syntax

DEVSQ(number1, [numberN], ...)

Parameter	Description
`number1`	The first number in the dataset.
`numberN`	Optional. Additional numbers or ranges containing numbers you want to include in the calculation.

Behavior

The DEVSQ function in Jspreadsheet is used to calculate the sum of squares of deviations from the mean in a data set. Here's how it handles different types of data:

Empty cells: Any empty cells within the range of values are ignored by the DEVSQ function.
Text: If the range includes text, the DEVSQ function will ignore these cells.
Booleans: Boolean values are interpreted as numbers: TRUE as 1 and FALSE as 0.
Errors: If any cells in the range contain errors, the DEVSQ function will return an error.

Common Errors

Error	Description
#DIV/0!	This error occurs if you are using the `DEVSQ` function with a dataset that only contains one number or all the numbers in your dataset are the same. Since there is no deviation from the mean, the function won't be able to calculate the sum of squares of deviations and will return this error.
#VALUE!	This error is returned if any of the arguments provided to the `DEVSQ` function are not numeric values.
#N/A	This error is returned if no data points are provided to the function.

Best practices

Always ensure that the range of values provided to the DEVSQ function contains numerical data. Any text values should be cleaned up or converted to numbers before running this function.

Be careful when using this function with datasets that contain only one unique number, as this will result in a #DIV/0! error.

Despite the fact that DEVSQ can handle Boolean values, it is generally advisable to convert these to numerical format to avoid confusion and potential errors.

Use the DEVSQ function in combination with other statistical functions for a deeper analysis of your data. For instance, you can use it to calculate the standard deviation or variance of a dataset.

Usage

A few examples using the DEVSQ function.

DEVSQ(1, 2, 3, 4, 5)        // Returns: 10  
DEVSQ(5, 5, 5, 5, 5)        // Returns: 0 – No deviation from the mean  
DEVSQ(TRUE, FALSE, 1, 0)    // Returns: 1 – Booleans coerced to numbers
