Wiki User. The weakness of the method is that it will be low in ecological validity compared to naturalistic observation. You want to test whether using green for advertising fast food chains increases the value of their products. Control in experiments is critical for internal validity, which allows you to establish a cause-and-effect relationship between variables. Researchers conducting experiments create control groups by specifically keeping certain variables . Here are 7 examples of quantitative observation. Jordan's mother informed the QP she had an appointment today and we could meet in the afternoon; however, she forgot about something she had to do in the afternoon, so she was busy unavailable.
