Arithmetic

How to solve

Sort the values from least to greatest; the median is the middle value (this drill always uses an odd count).

Steps

  1. Rewrite the list in increasing order.
  2. Cross off one value from each end until one remains.
  3. That middle value is the median.

Example

Median of 9, 2, 7, 5, 11?

  1. Sorted: 2, 5, 7, 9, 11.
  2. Middle (3rd of 5) is 7.

Answer: 7
