Details

AVERAGE adds up the numbers and divides the sum by how many there are. It takes the same arguments as SUM: cells, ranges and numbers separated by commas.

Empty cells and text in the range are left out, but zero counts. If you leave a day without sales empty, the average comes out higher than if you put 0 there.

The average is sensitive to outliers: one huge amount pulls it up noticeably. In such cases it helps to look at MEDIAN too.

Common mistakes

  • An empty cell and 0 aren’t the same thing: AVERAGE skips an empty cell but counts a zero.
  • There isn’t a single number in the range: the formula returns #DIV/0!.
  • Numbers stored as text are left out of the calculation, and the average is wrong without any error.
