Adaptive comparative judgement

Okay kiddo, have you heard of a game where you have to rank things in order from best to worst, like which ice cream flavor is your favorite? Well, sometimes people have to do this for real things like essays written by students or presentations made by adults.

And sometimes it's really hard to compare two things and say which one is better, especially when they are very different from each other. That's where a cool method called "adaptive comparative judgement" comes in.

Instead of trying to give each thing a score on its own, people who are doing the judging get to compare two things at a time and decide which one is better. They keep doing this over and over again until they have compared everything to everything else.

Then, a computer helps figure out which things are the best overall by looking at all the different comparisons that were made. It uses special math to figure out which things were judged the most consistently by the people doing the judging.

And that's how adaptive comparative judgement helps figure out which things are the best, even when they are really different from each other. It's like playing the game of ranking things with all your friends, but using math to make sure everyone agrees on the final answer. Cool, huh?
