Excel functions are as diverse as they are productive due to their level of precision and ease of implementation. For this reason, if you are carrying out an analysis of statistical data, we recommend that you learn how to use Office correctly and read this article with which you will learn **what the DEVIA2 and DEVPROM function are used for in Excel** .

On the other hand, it is very convenient to know other functions and actions such as calculating the inverse sine with ASENO and ASENOH in Excel. All of this helps you be more prepared for work.

## What is the DEVIA2 function?

The DEVIA2 function is an Excel statistical formula that allows you to **analyze a range of data** to return the sum of squares of deviations from the sample average.

Commonly, the DEVIA2 function is also known as “calculate SS” and takes into account numerical representations in the arguments. If the user inserts text, logical values, or leaves the cell empty for the argument, the function is ignored and an error is thrown in the result. However, OFFSET2 does take into account the value 0.

## What is the DEVPROM function?

The DEVPROM function is an Excel statistical property that allows obtaining the **average of the absolute deviations from the mean** of a data set; hence, the dispersion of a series of values is measured. This function accepts at least one argument and a maximum of 255 arguments in order to generate a result.

Usually, to calculate a result, the DEVPROM function uses two arguments. These must refer to a range of cells with values of type numeric. The first argument is required while the second is optional.

### What is the DEVIA2 and DEVPROM function used for in Excel?

The DEVIA2 and DEVPROM functions are very useful in statistical studies where **data analysis** is carried out with the aim of issuing valid conclusions. For this reason, it is necessary to install Microsoft Office on Windows, to know how these two functions are used in Excel and what their utility is.

### The DEVIA2 function syntax

The DEVIA2 function has a syntax that supports the **insertion of two arguments** and is expressed as = DEVIA2 (number1, [number2]). The first argument is required and refers to a number, a range of numeric values, arrays, or names that refer to numbers.

For its part, the second argument is optional and admits from 1 to a maximum of 255 additional arguments. It is important to note that the DEVIA2 function presents the error #NUM! if it does not find numerical values in its arguments to perform the calculation.

### The syntax of the DEVPROM function

If you already know how to use the CODE function in Excel, then the DEVPROM function will be easy for you since it uses a similar syntax with two arguments to be able to **generate a numeric value** .

The first argument must include a numeric value or a range that contains an array of numeric values. The second argument is optional and must also include numeric values. Therefore, the function is expressed in this way: = DEVPROM (number1, [number2])

### What is the DEVIA2 function used for

The DEVIA2 function is used in statistics to represent the **variability of a data set** taking into account a given sample. With this value, many companies that are dedicated to continuous production can work with a higher level of precision and reduce the error rate.

Therefore, the DEVIA2 function makes it easy to obtain a calculation that allows us to know how complicated the margin of errors can be and thus be able to carry out a successful plan.

### What is the DEVPROM function used for?

The DEVPROM function is used in the area of statistics in order to perform an analysis of **measures of dispersion** . For this, the data of a particular sample are taken into account.

Therefore, a result is obtained that allows knowing how dispersed the data is with respect to a set. If the DEVPROM function returns a value equal to 0, then the existence of equality of the data is interpreted. However, a high result indicates that there is wide variability in the data.
