Calculation breakdown
- Median
- Middle value of sorted list, or average of two middle values
Worked example
For the values 5, 9, 12 and 15 (sorted), the median is the average of 9 and 12, which is 10.5.
Assumptions
- The first four values are always included; toggle on values 5 to 8 to include them.
- The median is less affected by outliers than the mean.
How this calculator works
This calculator sorts up to eight numbers you enter and finds the middle value, or the average of the two middle values if there is an even count. The median is less affected by extreme outliers than the mean, making it useful for skewed data such as house prices.
Frequently asked questions
How do I skip a value?
Leave the toggle for that field off, and it will be excluded from the sorted list used to find the median.
What happens with an even number of values?
The median is the average of the two middle numbers once all included values are sorted.
Why use median instead of average?
The median resists distortion from outliers, so it's often a better 'typical value' for skewed data like incomes or house prices.
