What is the difference between accurate and precise?

Solution

BASIS FOR COMPARISON ACCURACY PRECISION

Meaning Accuracy refers to the level of agreement between the actual measurement and the absolute measurement. Precision implies the level of variation that lies in the values of several measurements of the same factor.

Represents How closely result agree with the standard value? How closely the results agree with one another?

Degree Degree of conformity Degree of reproducibility

Factor Single factor Multiple factors

Measure of Statistical bias Statistical variability

Concerned with Systematic Error Random Error

So, if the actual measurement is high in accuracy and precision, the result would be free from errors. If the actual measurement is precise but inaccurate, then the result is in disagreement with the expected one. If the actual result is accurate but imprecise, then there are huge variations in the measurements. And finally, if the actual measurement is neither accurate nor precise, then the result would lack correctness and exactness at the same time.

Hope this helps :)
