What would you do to improve the precision of an experiment?

The precision of an experiment is the condition where an experiment is very accurate and correct by performing various types of experiments. Some of the steps in improving the precision of an experiment are as follows-

1) Observations must be clearly made

2) Collecting data to the related problems or prior experiment analysis

3) Making proper use of the equipment (instruments)

4) Making a hypothesis on the basis of collected data

5) For precision, the test/experiments should be made with proper sample size.

6) Errors related to instruments and experimental errors should be reduced.

7) In some experiments, parallax must also be reduced.
