Accuracy is how close you are to the exact answer. Precise means how close you are mathematically with the data you have recorded. If you are precise but not accurate, you could be absolutely wrong. This is not the case when you are accurate.

accuracy is when an experimental value is in close agreement with a theoretical one; precision is when two or more trials give results that agree with each other (that is, they're said to be reproducible)
Reply:The answer is A: accurate but not very precise.





Accuracy deals with how close to the actual value something is (e.g if the answer is 9, than 1.0 is more Accurate than 1.00001).


Precision is either how exact the measurement is (e.g. 1.00001 is more Precise than 1.0), or how "scientifically" the measurement is taken (A micrometer will probably yield more precise measurements than a length of string)

Reply:If it is not consistently repeatable then it would have to be random first, and if the result is close every time then it would have to be systematic. Depending on what you are measuring maybe the method of measurement need to be addressed.
Reply:a. accurate, precise





Something that is close to the actual value is accurate, whereas something that is exact is precise. Looking at the answers, we see A as the only one beginning with accurate, so we know it's the answer.
