Expert Answer

Step 1

In chemistry, there are many ways to check the deviation of experimental data from the accurate value. These different methods provide the difference between accuracy and precisions of the experimental data which can be further used to calculate the error percentage in the experiment.

Step 2

Precision in any experimental data indicates how close the values are with each other. For example, if student A and B have set of 4 experimental data as given below;
