Single-case studies control outside variables by making a series of observations over time. By repeatedly measuring the behavior of the individual over time, researchers can help ensure that changes in behavior are not simply due to random fluctuations or external factors. This allows the researcher to attribute any observed changes in behavior to the manipulation or intervention being studied. Waiting to measure behavior until after treatment, using statistical tests to determine significance, and using a no-treatment control group for comparison are all techniques used in other types of study designs.
