I would have to go with C or D. But I could not give a direct answer.
They use the design of Nonexperimental Research.
<h3><u>What is Nonexperimental research?</u></h3>
- Research is defined as the creation of new knowledge and/or the use of existing knowledge in a new and creative way so as to generate new concepts, methodologies and understandings. This could include synthesis and analysis of previous research to the extent that it leads to new and creative outcomes.
- Nonexperimental research is research that lacks the manipulation of an independent variable, random assignment of participants to conditions or orders of conditions, or both. In a sense, it is unfair to define this large and diverse set of approaches collectively by what they are not.
Examples of Nonexperimental research.
- Commonly, non-experimental studies are purely observational and the results intended to be purely descriptive. For example, an investigator may be interested in the aver- age age, sex, most common diagnoses, and other characteristics of pediatric patients being transported by air.
