Explanation:

What's the difference between accuracy and precision?

When scoping a project, you want to be as close to the actual workload as possible. Defining the scope means that you and your client are figuring out and documenting a list of specific project goals. That could be features, functionalities, deliverables, deadlines, and ultimately costs of the project. Project scope helps with resource planning and time management of the project. Accuracy and precision are used in the context of measurement, e.g., the size of a project and therefore are both helpful when defining the scoping.

Accuracy and precision are alike only in the fact that they both refer to the quality of measurement, but they are very different indicators of measurement.

Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.

--------------------------------------------

A measurement that is precise means that it agrees with other measures of the same thing. In the sense of project scoping, let's take an estimation of workload as an example. If we estimate the size of several projects and they, in the end, are all close to or equal to what we predicted, then we can start to get a sense of the precision of our estimates. But first and foremost, each project needs to be as accurate as possible.
