Question

Quizplus · Accepted Answer

Natural experiments involve observing and comparing existing conditions or treatments, rather than manipulating variables as in a experimental design. Correlational studies assess the relationship between variables, but do not compare conditions or treatments. Retrospective design involves looking back at past data, which may include comparisons, but is not the primary focus. Real-time prospective designs involve manipulating variables to see their effects, rather than just comparing existing conditions or treatments.
