Question

Quizplus · Accepted Answer

An experimental study is the best choice for demonstrating a cause-and-effect relationship between an independent variable (the cause) and a dependent variable (the effect). In an experimental study, the researcher can manipulate the independent variable and control for other variables that may influence the outcome, thus providing strong evidence for causality. Observational and natural studies may suggest a correlation between variables, but they cannot establish causal relationships. Anecdotal evidence is based on individual experiences and cannot be used to draw general conclusions. Inferential studies involve making predictions or inferences based on data, but they do not necessarily demonstrate causality.
