- Median
- The middle value of a sorted set of numbers, less affected by outliers than the mean.
Frequently asked questions
It is the segment joining the midpoints of the legs, equal to the average of the two parallel sides. For 10 and 6 it is 8.
Yes. The trapezoid median and midsegment are the same line, parallel to the two bases.
The midsegment sits halfway between the parallel sides, so its length is exactly their average.
Area equals the median times the height, since the median is the average width of the trapezoid.
The Trapezoid Median Calculator uses the formula: Median (midsegment) = (Parallel side a + Parallel side b) ÷ 2. For example, with parallel side a of 10 and parallel side b of 6, the median (midsegment) is 8.0000.
