The specific way in which a variable is measured in a particular study is called the operational definition. The B in the ABCs of Applied Behavior Analysis stands for behavior. For this reason, a statistical analysis of a sample must report the approximate standard deviation, or standard error, of its results from the entire population. Scott defines this as "aggregates of organizations that are alike in some respect" (Scott p. 127). Unauthorized use of these marks is strictly prohibited.
