AP PSYCHOLOGY

Detailed explanation-1: -Of the various observational study designs, the descriptive design is the simplest. It allows the researcher to study and describe the distribution of one or more variables, without regard to any causal or other hypotheses.

Detailed explanation-2: -These are the kinds of considerations researchers must make when working through the design. The experimental method is the only research method that can measure cause and effect relationships between variables.

Detailed explanation-3: -Descriptive research design is a type of research design that aims to systematically obtain information to describe a phenomenon, situation, or population. More specifically, it helps answer the what, when, where, and how questions regarding the research problem rather than the why.

Detailed explanation-4: -It aims to determine if one variable directly impacts and causes another. Correlational and experimental research both typically use hypothesis testing, whereas descriptive research does not.
