Description: What makes a question a "statistical question"? So this whole class of just all this stuff that you might do with data to answer a question or try to figure out what's going on, or just to learn about the world, the whole class of things is called statistics. In statistics, variability is the degree to which data points are different from each other, the degree to which they vary.
