Efficient estimator

An efficient estimator is like having a superpower that helps you guess things really accurately with the least amount of mistakes. It's like being able to guess how many jelly beans are in a jar with only one or two wrong guesses, instead of having to guess a bunch of times which would take longer and could lead to more mistakes.

This superpower comes from a special formula that helps us make our guesses as close to the real answer as possible. It's like when you guess how many jelly beans are in a jar, you might look at the size of the jar, the size of the jelly beans, and how many layers there are. With an efficient estimator, we use similar tricks (but more math) to make better guesses.

When we have an efficient estimator, we don't need to keep making guesses over and over again because our guesses are really good. This can save us time and energy in the long run, and help us make better decisions based on the information we have.
