What does less accurate mean in science?

Answer 1

Accuracy in science is how close something to an accepted answer. Accuracy and precision are often confused. Precision is how exact an answer is, but it does not necessarily mean an answer is correct if something is exactly 1 meter long, someone who says that object is 0.9 meters long would be more accurate than someone who says it is 0.85, because .9 is closer to 1 than .85, however, .85 is a more precise answer because it is more exact, even though it is less accurate
