What is the best way to measure precision?Group of answer choicesModeStandard deviationMedianMean

To measure precision, the best option among the given choices is Standard Deviation.

Explanation:

1. Precision generally refers to the consistency or repeatability of measurements. It indicates how close multiple measurements are to each other, rather than how close they are to a true or accepted value.

2. Mean and Median are measures of central tendency, which summarize a set of data points into a single representative value but do not account for the spread or variability of the data.

3. Mode indicates the most frequently occurring value in a dataset, also not relevant to precision.

4. Standard Deviation, on the other hand, quantifies the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean of the dataset, thereby demonstrating high precision.

In summary, to evaluate how consistently a set of measurements is grouped together, standard deviation is the most appropriate measure of precision.
