A plain alphabetical sort puts "item10" before "item2", because it compares character by character without reading the number as a whole value. That's rarely what anyone wants from a sorted list. This sorts alphabetically, numerically, by length, or shuffles at random, and its numeric sort handles values like item2 and item10 in the order a person would expect.
When you'd use this
Sorting a list of names, file names with embedded numbers, or any column pasted from a spreadsheet. Or the opposite: shuffling a list into random order for randomized assignment or sampling.
Common errors
A list that sorts "wrong" alphabetically is often sorting correctly. Capital letters, numbers, and punctuation each hold their own position in standard character-code ordering, and that order doesn't always match intuition about where a given character should fall.
Frequently asked questions
Why does natural numeric sorting matter for a text list?
Because a plain string sort compares digit by digit instead of by value, so "item10" lands before "item2" ('1' beats '2' as the first character). Almost nobody wants that order. Natural sorting reads embedded numbers as whole values instead.
