AVERAGE
Definition
AVERAGE returns the arithmetic mean of the numbers it receives.
Syntax
=AVERAGE(number1, [number2], ...)
Arguments
| Argument | Meaning |
|---|---|
number1 |
The first value to include: a number, a cell, or a range such as B2:B5. |
number2, ... |
Optional extra values or ranges that join the same mean. |
Worked example
A gardener measures four seedlings in centimetres. The heights are in B2:B5 under a header in row 1.
| A: Plant | B: Height (cm) |
|---|---|
| Basil | 18 |
| Mint | 27 |
| Thyme | 20 |
| Sage | 35 |
Formula: =AVERAGE(B2:B5)
Result: 25. The heights add up to 100, and 100 divided by 4 plants is 25.
Practice
Cells D2:D4 hold three quiz results: 64, 70, and 91. Write a formula that returns the mean result.
- In D5, write an AVERAGE formula for D2:D4.
- D5 should show the mean of D2:D4.
Related functions
AVERAGE equals SUM divided by COUNT, so those two functions are the closest companions when you want to check how a mean was built.
Common mistake
Typing 0 in a cell where a measurement is simply missing drags the mean down, because AVERAGE counts that zero; leave the cell empty so it is ignored.
