Word Problems/acuracy and precision


let suppose i have 2 #s  98.65 and 98.078. then which is acuracy  and which is precise justify?

The more decimal places you have, the more precise your answer is. This is because the amount of error that can be made is reduced.
Accuracy refers to how close your answer is to the true value.

So say for instance you have calculated the mean of a set of figures to be 98.65 but the answer is actually 98.62 then your answer is accurate. If however you got 91.523, your answer is more precise but not accurate since it is not close to the true value of 98.62

Hope this helps,
