Average Calculator
Find the mean, median, mode, range and sum of any list of numbers.
Inputs
Formula
- Mean = Σx / n
- Median = middle value when sorted
- Mode = most frequent value
The mean is pulled by outliers, the median is not — which is why incomes are usually quoted as a median. Seeing all three together tells you far more about a data set than any one of them alone.
