# Understanding Functions in Google Sheets

**Functions-What are they?**

**Functions** are a predefined formula that perform calculations using particular values in a certain order.

**Why use them?**

Functions are particularly useful in the realm of education as they allow you to analyze sets of date quickly and efficiently. For example, functions can be used to quickly calculate the sum, average, number of items in a set of data. More advanced users can write their own

**Understanding the Anatomy of a Function:**

As seen in the photo above, In order to call a function, enter an equal sign in a cell to call the function. Then add the function name and put the data range you wish to apply the function to in between parenthesis. Alternatively, you can call the function using the Functions button located in the toolbar:

If there are MULTIPLE arguments inside a function they need to be separated by a comma. As seen in the image below:

**Common Functions And Their Uses:**

Here are a list of some common functions and their uses (these are the functions you will need to know should you choose to become a Google Certified Educator)

**SUM**: This function**adds**all of the values of the cells in the argument.**AVERAGE**: This function determines the**average**of the values included in the argument. It calculates the sum of the cells and then divides that value by the number of cells in the argument.**COUNT**: This function**counts**the number of cells with numerical data in the argument. This function is useful for quickly counting items in a cell range.**MAX**: This function determines the**highest****cell value**included in the argument.**MIN**: This function determines the**lowest cell value**included in the argument**COUNTIF:**Returns a conditional count across a range.**UNIQUE:**Returns unique rows in the provided source range, discarding duplicates. Rows are returned in the order in which they first appear in the source range.**SUMIF:**Returns a conditional sum across a range.**SORT:**Sorts the rows of a given array or range by the values in one or more columns.**FILTER:**Returns a filtered version of the source range, returning only rows or columns that meet the specified conditions
