What is the quickest and least expensive way to study development?
Why would a scientist conduct a cross-sectional study ? It is the quickest and least expensive way to study development over time; it is designed to compare groups of people who differ in age but are similar in other important characteristics.

What type of research is most controlled?

What is a two group design?

Which type of research has only one subject?
“Single subject research (also known as single case experiments ) is popular in the fields of special education and counseling. This research design is useful when the researcher is attempting to change the behavior of an individual or a small group of individuals and wishes to document that change.
