It is known that through optimal sample definitions and data collection, test norms are not absolute. With this they can change with time or with a different norm group. Knowing this, I need help with developing a description of the information that can be anticipated when collecting through looking at the proposed instrument when assessing childhood aggression. Then explain how one would optimally define the given sample and collect the data if allotted UNLIMITED resources (The key phrase is unlimited resources). Finally, explain advantages and disadvantages of the chosen data collection method. Please also include at least one journal reference.
