Formula Friday - Average

Similar to the Sum formula, using the Average formula in Excel is fairly quick and easy.  Just like the sum formula, the average can be used to average both consecutive and non-consecutive numbers.

To use the formula for consecutive numbers:
-Type '=average(Number1:Number2)'
-Press Enter
-Example 1:
-In this example I want to average the total units for Sunday through Saturday in cell B9
-In cell B9 type '=average(B2:B8)'
-Press Enter

 
-Now you will see the result of 5
 
-To see the formula, click back into cell B9 and you will see the formula in the Formula Bar
 
To use the formula for non-consecutive numbers:
-Type '=average(Number1,Number2)'
-Press Enter
-Example 2:
-In this example I want to average the total units for Sunday and Saturday in cell B9
-In cell B9 type '=average(B2,B8)'
-Press Enter
 
-Now you will see the result of 5
 
-To see the formula, click back into cell B9 and you will see the formula in the Formula Bar
 
To use the formula for consecutive and non-consecutive numbers:
-Example 3:
-In this example I want to average the units for Friday, Saturday and Sunday in cell B9
-In cell B9 type '=average(B2,B7:B8)'
-Press Enter

 
NOTE: The difference between the consecutive and non-consecutive numbers is the difference of using either ' : ' or ' , '.  For consecutive numbers, use the ' : ' between the first and last number. For non-consecutive numbers, use a ' , ' between the numbers.

-Now you will see the result of 4

 
-To see the formula, click back into cell B9 and you will see the formula in the Formula Bar
 
As I explained with the Sum formula, there are multiple ways to insert the average formula into the spreadsheet.
1. Type the formula in as described above
2. Use the "Insert Icon" function and type in 'Average' (Follow the same steps as in the Sum formula post)
 
 
3. On the Home tab, in the Editing section, click the AutoSum function drop down menu
-Click Average
4. On the Formulas tab, in the Function Library Section, click on the AutoSum function drop down menu
-Click Average
 

The 3rd and 4th options work best for summing consecutive cells. That being said, you can make adjustments to the formula to sum non-consecutive cells or a combination of both.

Excel ya later!
