Question

what Is difference between accuracy and precision

Answer 1

accuracy is the perfect (0.00000009 also) number/concept,a single digit also taken into consideration.

Precision is for easy calculation purpose.

For example,

we take g= 9.8 m/s^2(accuracy)
g=10m/s^2(precision)

also here we sometimes take 0.9 as 1,it is precision .

In physics accuracy is having more important but without precision you can not solve a complex problem.

(I have given the example of g at a place where correct value is 9.8,at some places correct value is 10 too,so accuracy can be 10 at those places)

Thanks.

Answer 2

Precision means the closeness of various measurements for the same quantity. Accuracy is the agreement of a particular value to the true value of the result.
