Document Summary
Five basic research strategies: experimental, non-experimental, quasi-experimental, correlational, and descriptive. The correlational strategy does not attempt to explain the relationship and make no attempt to manipulate, control, or interfere with the variables. The important factor is that the researcher simply measures the two variables being studied. The measurements are then examined to determine whether or not they show any consistent pattern of relationship. A correlational study can involve measuring more than two variables but usually involves relationships between two variables at a time. In the correlational research strategy, two variables are measured and recorded for each individual. The measurements are then reviewed to identify any patterns of relationship that exist between the two variables and to measure the strength of the relationship. The individual is intended to be a single source, not necessarily a single person. A correlational study could be described as requiring two scores from the same individual.
