Wikijunior:The Book of Estimation/Errors

Do you still remember that in measurements, there is no way of getting the exact value? Since our measurements are never accurate, there must be a difference between our measurements and the exact, unobtainable value. That's why we have error. In this chapter, we will learn how to calculate different kinds of error. Sometimes, we will assume that we know the exact value. Other times, we will try to figure out the largest possible error that will appear.

Before you start
Skim through the chapters before this one except estimation in calculation. Make sure you understand everything in there. Also, take a look at this problem. Remember it – we will be using it for the rest of the chapter!
