What are random errors?

Random errors are small, unexpected mistakes that happen when you measure or count something.

Imagine you're trying to see how many jellybeans fit in a jar. You count them carefully, but sometimes you might miss one or accidentally count an extra, just because your eyes got tired or you blinked at the wrong moment. These little mix-ups are random errors.

Think of it like taking steps to walk across a room. Most of the time, each step is exactly the same length. But sometimes you might take a tiny extra step or skip one, not because you're trying to be tricky, but just because your legs feel a little wobbly that day. These tiny changes in step size are like random errors; they happen without any pattern.

Random errors don’t mean you’re wrong, just that you're a little bit off most of the time. If you count jellybeans again, or take more steps, those tiny mistakes usually average out and make your final answer pretty close to what it really is. That's why scientists do experiments many times, so they can catch these little wobbles and get a clearer picture!
