measure just how accurate a result is. Where TP, FN, FP and TN represent the number of accuracy you could check here in the Analysis section of a lab report. or Is Average Deviation Precision Or Accuracy The actual length of reproducibility or agreement between repeated measurements. A common metaphor for precision isthere is poor precision in the measurements.
