Relative error is the ratio between​

Answer 1

Answer:

Relative error (RE)—when used as a measure of precision—is the ratio of the absolute error of a measurement to the measurement being taken. In other words, this type of error is relative to the size of the item being measured. RE is expressed as a percentage and has no units.

Answer 2

It is the ratio between mean absolute error to the mean value.

• It is used as a precision metric.
• It is the ratio of a precise measurement's absolute inaccuracy to the measurement itself.
• In other words, the considerable size of the item being typically measured accurately determines the sort of possible mistake.
• It has no independent units and is delivered as a specific percentage. It's the proper ratio of the mean absolute error to the measured quantity's mean value.
