Calibration (statistics)

Calibration is a way we make sure that the numbers we use to make decisions are accurate.

Imagine you have a toy car that you want to use to measure how far you can roll it. You want to know how many feet it goes each time you roll it. But first, you need to make sure that the car is accurate.

To calibrate the car, you could use a ruler to measure how far it rolls. You would measure how far the car rolls three times and take an average of those three distances. This would give you a better idea of how far the car goes when you roll it.

Using this approach, you can be more confident that the numbers you get from the car are more accurate, and you can make better decisions about how far to roll it, or how to use it in other ways.

Calibration is used in many areas, such as science or medicine, where accurate measurements are crucial, and we need to make sure the tools we use are reliable to make definitive conclusions.
