Question

difference between accuracy and precision ?

i dont seem to get the difference.. plz give quick explantion

Answer 1

my notes has :

Accuracy refers to the closeness of a measurement to the true or accepted value. An electronic balance that is often calibrated with a standard mass will measure mass more accurately than an old, triple beam balance that has been dropped several times over the years.

Precision refers to the agreement among a set of measurements made of the same quantity in the same way. This is a question of repeatability or consistency: are the measurements consistent when taken more than once?

Answer 2

Accuracy means getting a result that is close to the real answer. Precision means getting a similar result every time you try.

Think of shooting at a target: Being accurate means you hit the bull's eye. Being precise means hitting the same spot on the target every time.

Answer 3

oh accuracy refers to single time measurement, we get close or not

Answer 4

precision refers to repeated measurements, we get close each time or not

Answer 5

Answer 7

You are correct. Here a little tips. You can think precision as being consistent.

Answer 8
