What is the difference between accuracy and precision in dimensional analysis?

• Accuracy is the closeness of a measured value to the true value, while precision is the closeness of measured values to each other.

• Accuracy is the closeness of a measured value to the average value, while precision is the closeness of measured values to each other.

• Accuracy is the closeness of a measured value to the median value, while precision is the closeness of measured values to the mode value.

• Accuracy is the closeness of a measured value to the maximum value, while precision is the closeness of measured values to the minimum value.
