Watch the video for a brief overview of several common types of variables: Can’t see the video? Click here. A “variable” in algebra really just means one thing—an unknown value. However, in statistics, you’ll come across dozens of types of variables. In most cases, the word still means that you’re dealing with something that’s unknown, but—unlike in algebra—that unknown isn’t always a number. Some variable types are used more than others. For example, you’ll be much more likely to come across continuous variables than you would dummy variables. The following lists are sorted into common types of variables (like independent and dependent) and less common types (like covariate and noncomitant).
