ELI5: Explain Like I'm 5

Pareto chart

Okay kiddo, imagine you have a big pile of toys in your room. Your mom says you need to clean it up, and you start picking up toys one by one. After a few minutes, you notice that some toys are taking up more space than others, and you're spending a lot of time picking them up.

A Pareto chart is like a special kind of graph that helps you understand which toys are taking up the most space, so you can focus on picking those up first.

Let's say you have 10 toys in your room: a teddy bear, a ball, a puzzle, some blocks, a car, a doll, a book, a stuffed animal, a game, and a train. You start picking them up one by one, and after a few minutes, you have a pile of toys on your bed.

Now you make a tally chart, which is like a list of how many of each toy you picked up. You make a tally for each type of toy, and count how many times you picked it up.

After counting up your tallies, you notice that most of the toys in your pile are blocks, cars, and dolls. The teddy bear, ball, puzzle, book, stuffed animal, game, and train only make up a small part of the pile.

That's where the Pareto chart comes in. You make a special graph that shows each type of toy and how many times you picked it up. You put the toys in order from the most picked up to the least picked up, and draw bars to show how many of each type you picked up.

The tallest bar on the Pareto chart will be for the toy you picked up the most, and the shortest bar will be for the toy you picked up the least. This helps you see which toys are taking up the most space, so you can focus on picking those up first.

So now you know that you need to pick up the blocks, cars, and dolls before you pick up the teddy bear, ball, puzzle, book, stuffed animal, game, and train. And that's how a Pareto chart can help you clean up your toys!
