Variables are then studied to examine patterns of relation, covariation, and cause and effect. In sum, researchers need to be careful in making sure that their interpretations of interrupted time-series analyses take into consideration as much information, both empirical and nonempirical, as possible. In research, variables are any characteristics that can take on different values, such as height, age, temperature, or test scores.

One or more of these variables, referred to as the factors of the study, are controlled so that data may be obtained about how the factors influence another variable referred to as the response variable, or simply the response.
