False discovery rate

Alright kiddo, let me try to explain this to you easily. Imagine you have a puzzle box that has many compartments, and you want to find the piece that completes the puzzle. You have to open each compartment to see if the piece is there.

This is like when scientists do experiments and look for interesting things. They test many ideas, like opening the compartments of the puzzle box. They search for something that might be different or special - like the puzzle piece.

But sometimes, when scientists test too many ideas, they get some wrong results, like opening empty boxes in the puzzle box. This is called a false positive.

The false discovery rate is like counting how many boxes they went through before finding the actual puzzle piece. If they opened a lot of empty boxes before they found the piece, then the false discovery rate is high.

Scientists use the false discovery rate to make sure that they don't get excited about things that aren't really there. Just like you don't get excited about an empty puzzle box.

Hope that helps!
