Use the AVERAGE function to find the mean in a set of data
Excel has several functions that calculate the central trend in a set of data: AVERAGE , MEDIAN and MODE . The most commonly obtained measure of central tendency is the simple mean (mean) and is calculated by adding a group of numbers and then dividing by the number of those numbers.
Here’s how to find the arithmetic mean using the function AVERAGE .
Remark . These instructions apply to Excel 2019, 2016, 2013, 2010, Excel for Mac, and Excel for Office 365.
Syntax and arguments of the function AVERAGE
Function syntax refers to the layout of the function and includes the function name, parentheses, comma separators, and arguments. Function Syntax AVERAGE :
= СРЗНАЧ (число1, число2, ... Number255)
 Number 1 (required) are the data over which the function must find the mean value.
 Number from 2 to 255 (optional) is the additional data you want to include in the average calculation. The maximum number of entries allowed is 255.
Input options for a function and its arguments include:

Enter a complete function in a worksheet cell

Enter function and arguments with Dialog Function

Enter functions and arguments with Excel shortcut Average function
Excel AVERAGE function example
Excel has a shortcut to enter a function AVERAGE sometimes called car average because of its association with the more familiar function AutoSum located on House tab on the adhesive tape .
The steps below describe how to enter the function: AVERAGE as shown in the fourth line of the sample image above, using the shortcut mentioned above.

Click cell D4, true the results of the formula are displayed.

Click House tab on tape .

Click down arrow next to the button AutoSum on the adhesive tape to open the dropdown menu.

Select The average in the list to enable the function AVERAGE in a cell D4.

highlight cells A4 – C4 to enter these references as arguments to the function, and press the . key Enter on keyboard.

Number 10 should appear in the cell D4; is the average of three numbers ( 4 , twenty and 6) .
Best Practices for Using the AVERAGE function

You can add individual cells as arguments instead of a running range, but you must separate the cell reference with a comma.

Excel ignores blank cells, text input, and cells with boolean values ( TRUE or FALSE ).

By default, if you make changes to the data in the selected cells after entering the function, it will be automatically recalculated to reflect the changes.
How AutoAverage selects ranges

The default range contains only cells that contain numbers.

Function AVERAGE must be entered at the bottom of a column of data or at the right end of a row of data because it searches for numeric data first, then to the left.

Since the function AVERAGE , essentially guesses the range it chooses for the Number argument; You should always check the accuracy before pressing any key. Enter on the keyboard to complete the function.
Empty cells vs. empty cells
When it comes to finding averages in Excel, there is a difference between blank or blank cells and cells with a zero value. Empty cells are ignored by the function AVERAGE which can be very useful as it is very easy to find the mean of noncontiguous data cells.
By default, Excel displays zero in zerovalued cells, such as the result of a calculation, but if this option is disabled, such cells remain blank, but are included in the average calculations.
