Question

Quizplus · Accepted Answer

Quasi-experimental designs are used to study causal relationships when researchers cannot randomly assign participants to groups or control all variables, which is often the case with preexisting conditions like smoking. Unlike true experiments, quasi-experiments lack random assignment, making them suitable for studying the effects of antecedent conditions like smoking on outcomes such as lung cancer.
