What are the 4 types of research design?

The design of a research topic is used to explain the type of research (experimental, survey, correlational, semi-experimental, review) and also its sub-type (experimental design, research problem, descriptive case-study). There are three main sections of research design: Data collection, measurement, and analysis.

What are the advantages of hypothesis tests over confidence intervals?

The principle of proposing a hypothesis, reformulating it into a “null” form, and then testing the robustness of that null hypothesis is fundamental to scientific inquiry and the entire process of advancing knowledge. It’s not perfect, but it is the best we have. Neither is it limited to conventional “science”; it is employed by all credible seekers after ‘truth’. Read the full article for more details.
