A scientific study in which detailed information is obtained about complex issues, sensitive topics or life experiences. The information provides a deeper understanding and is used to generate new theories or hypotheses. A research design that resembles an experimental design but has no random assignment. This design allows researchers to look at relationships between variables rather than causes and effects. Also see experimental, random assignment.
Individuals record their responses to questions or statements.
A statistical procedure that is used to describe linear relationships between dependent variables and independent variables. Individuals are placed into groups or treatment conditions in such a way that each person has an equal chance of being selected for any group or treatment. In addition, placement of any individual into a group or treatment condition does not influence the placement of any other person. A group of persons are selected from a population in such a way that each individual has an equal chance of being chosen. In addition, the selection of one person does not influence the chances of other people being selected.
