Start with three numbers, say 5, 17, and 23. Their median (middle value) is 17. Find a fourth number so that the mean of all four is 17. This number must be 23 (4 x 17 – 5 – 17 – 23). Repeat the ...

If there is an even number of items of data, there will be two numbers in the middle. The median is the number that is half way between these two numbers. To find the median, put all numbers into ...

We know that the median is the middle number in a set of ordered data. It divides the set of ordered data into two halves. We also know that for a set of \(n\) ordered numbers, the median is the ...
