Accuracy Vs Precision Definition. Precision is about exactness. As against this precision is concerned with random error which occurs periodically with no recognisable pattern.
It is possible to be accurate without being precise and be very pre. Apr 27 2020 Precision is an independent variable from accuracy entirely even though the two terms are often used relatively interchangeably. Accuracy is a weighted arithmetic mean of Precision and Inverse Precision weighted by Bias as well as a weighted arithmetic mean of Recall and Inverse Recall weighted by Prevalence.
Accuracy refers to how close measurements are to the true.
Precision - how close two or more measurements are to each other regardless of whether those measurements are accurate or not. Accuracy refers to the closeness of a measured value to a standard or known value. Precision may be established without the availability of a gold standard as it represents the scatter of the data rather than the exactness accuracy of the reported result. Precision is how close measurements or the closeness of the measurementsresults with each other.
