The hawthorne effect: when you are observed or part of a study, you do better. From theory, we derive hypotheses: a prediction, a cause-effect relationship, manipulation i. e. studying and exam performance. Experimental and control groups: experimental group, gets the manipulation, is exposed to the independent variable, control group, does not get the manipulation/treatment, not exposed to independent variable. Designs: quasi-experimental, lacks the element of random assignment to treatment or control (limited, the participants involved have an innate characteristic that is the variable being tested i. e. study on children with diabetes. Ethics of a study: participants rights & well-being. Informed consent: requirement that researchers must give as much information as possible about the purpose, procedures, risks, and benefits of the study so that a participant can make an informed decision about whether or not to participate.
