Question

What is precision?

Answer 1

Hint: We have to remember that the precision can be remembered using word repeatable whereas accuracy can be remembered as correct. Reliability and consistency must be known to define precision.

Complete answer:
We also remember that the precision can be seen or observed as the exact measurements in a strictest manner. In other terms it can also be defined on the basis of reliability and consistency of the measurement of an experiment. Now we can look at the difference between accuracy and precision.
Accuracy can be defined as the level of correctness of a measurement to its true or original value whereas precision defines the exact measurements to its original value. In accuracy, only one factor is used for measuring while in precision multiple factors are used for measurement. Accurate things can be precise in most cases but vice versa is not true.
We can look at an example to study accuracy and precision:
While doing an experiment, the amount of compound to be weighed is $3g$. If we weigh three times we get three values $2.9g$, $2.8g$ and $2.96g$ this system of value is accurate but not precision. While weighing again to get three values we get $2.9g$, $2.9g$, and $2.9g$ this system of values can be called precision but not accurate.

Note:
We need to remember that the Precision can be separated into conditions which are: Repeatability arises when the conditions are identical and repeated measurements are taken during a short period of time. Reproducibility arises when the same measurement occurs but a different instrument is used. Accurate things can be precise in most cases but vice versa is not true.
