How does the Median Calculator work?
Sort the numbers from smallest to largest. The median is the middle one, or the average of the two middle ones when the count is even.
Quartiles are the medians of the lower and upper halves. Leave a box empty to skip it.
Frequently asked questions
What if there is an even number of values?
Average the two middle numbers. The median of 2, 4, 6, 8 is 5.
When is median better than mean?
When there are outliers, like incomes or home prices, since extreme values pull the mean.
What is the interquartile range?
The third quartile minus the first. It measures the spread of the middle half of the data.
Can a data set have two medians?
No. A set has one median. With an even count, you average the two middle values to get it.
