Myers, and G. Hunter have reached generations of students and practitioners. Some discussion of experimental design in the context of system identification model building for static or dynamic models is given in  and . Laws and ethical considerations preclude some carefully designed experiments with human subjects. Legal constraints are dependent on jurisdiction. Constraints may involve institutional review boards , informed consent and confidentiality affecting both clinical medical trials and behavioral and social science experiments.

If they judge the unattractive defendant more harshly, this might be because of his unattractiveness.
But it could be instead that they judge him more harshly because they are becoming bored or tired. In other words, the order of the conditions is a confounding variable. The attractive condition is always the first condition and the unattractive condition the second. Thus any difference between the conditions in terms of the dependent variable could be caused by the order of the conditions and not the independent variable itself.
There is a solution to the problem of order effects, however, that can be used in many situations.
You are here
For example, some participants would be tested in the attractive defendant condition followed by the unattractive defendant condition, and others would be tested in the unattractive condition followed by the attractive condition. With counterbalancing, participants are assigned to orders randomly, using the techniques we have already discussed.
Thus random assignment plays an important role in within-subjects designs just as in between-subjects designs. Here, instead of randomly assigning to conditions, they are randomly assigned to different orders of conditions. In fact, it can safely be said that if a study does not involve random assignment in one form or another, it is not an experiment.
An efficient way of counterbalancing is through a Latin square design which randomizes through having equal rows and columns. For example, if you have four treatments, you must have four versions.
Like a Sudoku puzzle, no treatment can repeat in a row or column. For four versions of four treatments, the Latin square design would look like:. There are two ways to think about what counterbalancing accomplishes.
