Question

How can precision be improved?

Answer 1

In order to answer the above question, we will be looking up at the chapter of units and measurements. We will be looking up to the errors that occur during measurements.

Complete step by step answer:
First of all, what do we mean by the word precision? Precision refers to how close various sample measurements are to one another, while accuracy refers to how close certain sample measurements are to the true measurement.
For example, The United States Mint, produces pennies to a minimum of $2.5$ grams. If we weigh a penny five times, the precision of our measurements is determined by how close each of our five measurements is to the next, but the accuracy of our measurements is determined by how close the measurements are to $2.5$ grams.
Now we know what exactly the word precision means. But how can someone improve the precision of their measurement?
Paying careful attention to detail, correctly using tools, and growing your sample size will all help improve precision. We have to make sure that the equipment is configured, operational, clean, and ready to use. Using equipment that isn't working properly will cause the results to be all over the place, and debris stuck to the equipment will disrupt mass and volume measurements. Increasing the number of samples taken improves the chances of discovering the "truth”. As in the above example, when weighing a penny, weighing it ten times rather than five times is more likely to yield an average that is closer to the true weight of $2.5$ grams.

Note:
It is very important to note that there is a very thin line of difference between accuracy and precision. Precision refers to how close various sample measurements are to one another, while accuracy refers to how close certain sample measurements are to the true measurement.
