What are error sources?

Imagine you're trying to draw a straight line on paper, but your pencil keeps wobbling, that’s like error sources! They’re things that make our answers or measurements not perfect.

When you're drawing, the wobbles can come from many places. Maybe your hand isn’t steady, that's one error source. Or maybe the paper is crumpled, another error source. Each of these little problems adds up to make your line look messy instead of straight.

Think about measuring the length of your room with a tape measure. If you're not careful, you might miss a step or two, that’s like a measurement error. Or maybe your tape measure is broken and gives wrong numbers, that's another kind of error source.

Every time something goes slightly off track, it adds to the final result, just like how wobbles make your line not perfectly straight. Error sources are everywhere, they're like little helpers that remind us nothing is perfect!
