Accuracy: Accuracy refers to how close a measurement or estimate is to the true value. It measures correctness rather than consistency.
Variability: Variability describes how spread out or diverse a set of measurements is. It is related to precision as it measures how consistent or inconsistent the measurements are.
Standard Deviation: Standard deviation measures the average distance between each measurement and the mean of all the measurements in a dataset. It provides information about variability and precision within a dataset.
