AP PSYCHOLOGY

Detailed explanation-1: -A natural experiment is not considered a true experiment because the researcher is not able to manipulate or control the variables.

Detailed explanation-2: -Since such real-life events cannot be manipulated or prearranged, natural experiments are quasi-experimental designs rather than true experiments. Also called naturalistic design; naturalistic research.

Detailed explanation-3: -Because natural experiments do not randomize participants into exposure groups, the assumptions and analytical techniques customarily applied to experimental designs are not valid for them. Rather, natural experiments are quasi experiments and must be thought about and analyzed as such.

Detailed explanation-4: -Natural experiment studies (NES) combine features of experiments and non-experiments. They differ from planned experiments, such as randomized controlled trials, in that exposure allocation is not controlled by researchers.

Detailed explanation-5: -The term true experiment is sometimes used to refer to any randomized experiment. In other instances, the term true experiment is used to describe all studies with at least one independent variable that is experimentally manipulated and with at least one dependent or outcome variable.
