Statistical Attributes

Lesson

An attribute is defined as a specific characteristic or feature of a given subject. When we talk about statistical attributes, we mean the specific topic or subject that we want to investigate. If we can clearly identify the statistical attributes in a research project, it helps us generate clear research questions so we can make useful conclusions.

Let's look at some examples and practice identifying statistical attributes.
