Sort a list from smallest to largest

Put the numbers in a list in order, which makes the median and mode easy to spot.

Open in Trident

Sorting puts a list in order. Once sorted, the smallest and largest values sit at the ends, the median sits in the middle, and repeated values (the mode) sit next to each other.

The example list is 5, 2, 9, 1, 7. Sorted, it becomes 1, 2, 5, 7, 9.
