There’s a difference between accuracy and precision, and these two words should not be used interchangeably. Accuracy describes how close you are to a known value.Precision on the other hand refers to how reliably you can get the same results, over and over again.
In science, it is our objective to gather lab data that is both accurate and precise. But sometimes, this ability is limited by the measuring instruments that we use, like in today’s lab.
