Question

Quizplus · Accepted Answer

A hypothesis is a statement that predicts or accounts for a set of phenomena based on existing knowledge and observations. It is a tentative explanation that can be tested through research and experimentation. A theory, on the other hand, is a well-established explanation that has been supported by empirical evidence and can predict and explain a range of phenomena. An operational definition is a clear and concise description of how a variable is measured in a particular study. A double-blind study is a research method in which neither the participants nor the researchers know who is receiving the treatment or the placebo.
