Why is it so important for measurements in an experiment to be accurate and precise?

Answer and explanation;

-Accuracy is the closeness of measured value to correct value, while precision is the closeness of measured value to other measured values .

- It so important for measurements in an experiment to be accurate and precise because you need to get accurate and precisise results.

-If your measuring instrument always gives values that are closely grouped - precise - they will be of little value if the calibration of the equipment is such that the measured values are not correct - accurate. Similarly, if the equipment is calibrated correctly but your measurements vary wildly you will not know which measurement, if any, is correct.
