Scientific Method and Case Study
Blank blank
Psychologists use a variety of research methods to study behavior. Three of the main research methods used are: case study, correlation study, and experiment.
A. Discuss one advantage of each research method listed above:
A typical advantage of a case study is that they provide detailed information about the case and what is being studied.
A typical advantage of a correlation study is that they examine, reveal, compare, test, and describe relationships between two variables; they also can be efficient and save time and money.
A typical advantage of an experiment is that they may establish cause and effect relationships also; they allow the researcher to distinguish between placebo and real effects.
B. Discuss one disadvantage of each research method listed above:
A disadvantage to a case study is that their results cannot be generalized. They also cannot be used to establish cause and effect relationships.
A disadvantage to a correlation study is that they are prone to inaccurate reporting.
A disadvantage to an experiment is that they reduce external validity.
C. For each method above, explain a key characteristic of the basic approach you could use to reach a scientific conclusion about the relationship between taking vitamin J and improving memory.
Case study: A study of one person or functional unit.
Correlation study: Discussion of the relationship or correlation between vitamin J and memory.
Experiment: Establishment or use of vitamin J, control, or placebo control groups.
