Explanation of the AVERAGEIFS function
The AVERAGEIFS function allows you to evaluate for multiple criteria with the following argument structure:
- criteria_range1, criteria1
- criteria_range2, criteria2
- Note: You can input up to a max of 127 [criteria_range, criteria]
In the image below I purposely typed a few commas to force the argument description to show multiple criteria.
- AVERAGEIF –> evaluates for only 1 criteria
- AVERAGEIFS –> evaluates for multiple criteria. Note: You can still use the AVERAGEIFS function if you only have 1 criteria. In this way it will act like an AVERAGEIF function.
Example data used to explain how the AVERAGEIFS function works
- 3 different colors
- each color has 3 different sizes
- 2 locations (color coded to easily distinguish them apart)
- Quantity sold at each of the 2 locations
1. average_range (1st argument)
The average_range is what the AVERAGEIFS function will use to average the numbers whenever it finds a match for your criteria in the critera_ranges.
2. criteria_range1, criteria1 (2nd and 3rd arguments)
The AVERAGEIFS function will use the criteria_ranges to find a match against your criteria for each pair of [criteria_range, criteria] that you provide.
Note: You can input up to 127 pairs of [criteria_range,criteria].
How does the AVERAGEIFS function work?
You should use the AVERAGEIFS function if you need the average of a set of numbers when multiple criteria are true.
When the function finds a match for each criteria in the corresponding criteria_ranges (which is evaluated for each pair of [criteria_range,criteria]), it will average the corresponding numbers from the average_range into the final result.
For each row within your data set:
- If at least 1 of the criteria does not match the value from its criteria_range –> the corresponding value from the average_range is ignored
- If each criteria matches the value from its criteria_range –> the corresponding value from the average_range is included in the average
Keep in mind the AVERAGEIFS function syntax when reading the Formulas shown below… =AVERAGEIFS(average_range,criteria_range1,criteria1,….<all the way to>….,criteria_range127,criteria127)
Explanation of results
- Blue shirts sold in location A = (8 + 19 + 6) / 3 = 33 / 3 = 11
- White and Large shirts sold in location B = 19 / 1 = 19
- Black and Medium shirts sold = (13 + 2) / 2 = 15 / 2 = 7.5
- All shirts sold in location B = (18 + 2 + 15 + 9 + 17 + 19 + 12 + 2 + 1) / 9 = 95 / 9 = 10.56
