Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.
The method, explained
Mean = sum of all values ÷ number of values. Median is the middle sorted value, or the average of the two middle values.
For 2, 3 and 10, the mean is 5, the median is 3 and the sum is 15.
What to keep in mind
Separate values with spaces, commas or semicolons. Use a dot for decimals and do not use thousands separators. Each value has equal weight; this is not a weighted average.
Common questions
Does zero count?
Yes. Zero is a valid observation and is included in the count.
When is the median more useful?
The median is less affected by extreme values. Comparing mean and median can help reveal a skewed set of numbers.
