ELI5: Explain Like I'm 5

How to Lie with Statistics

Alright kiddo, imagine you have a chocolate cake and 5 friends who want a slice. Now, you want to make sure everyone gets a fair share, so you cut the cake into five equal pieces.

But, let's say one of your friends is really good at eating cake and can eat a bigger slice than the others. Now, to make sure that friend gets a fair share, you might cut their slice a little bigger than the others.

This is kind of like how people can "lie" with statistics. They can manipulate the numbers to make things seem more or less important than they really are.

For example, let's say there's a study that shows people who eat more vegetables live longer. But, someone who wants to "lie" with statistics might only show you part of the study, like the fact that people who eat more carrots live longer. They leave out the part that says people who eat more broccoli or spinach or other veggies also live longer.

This makes it seem like carrots are magically saving lives, when really it's just a small part of a bigger picture.

Another way people can "lie" with statistics is by using big numbers or percentages without giving you the full context. Let's say you're trying to convince your mom to buy you a new toy. If you tell her the toy costs $10 and that's it, she might say no. But if you say the toy only costs 10% of your weekly allowance, it sounds like a much better deal.

But, if you leave out the fact that you already spent most of your allowance on candy, then the 10% doesn't mean as much.

So, always make sure to ask questions and get the full story before believing any statistics or numbers. And remember to share your cake equally, even if one friend can eat more than the others!
