Which two of the following are commonly understood to be advantages of case studies? Select the second correct option.

A case study is an intensive, in-depth analysis of an individual, group, or event. Its strengths and weaknesses are distinct from experimental methods. A major advantage is that it allows researchers to study rare phenomena. Another key strength, as identified here, is the depth of information gathered. Researchers can use a variety of methods (interviews, observations, psychological tests) to build a rich, detailed picture of the case, providing insights that a large-scale, quantitative study might miss.
