About This Chapter

Watch research design and analysis video lessons to learn about experiment validity, correlations, research ethics and more. Each lesson is accompanied by a short multiple-choice quiz which you can use to check your understanding of these topics.

Research Design and Analysis

What is research design? Find out in our lessons which will teach you about the basic types of research design and these include case studies, survey studies and experiments, to name a few. You'll also get the chance to look into the differences between cross-sectional and longitudinal studies. Find out what it takes for something to be classified as a true experimental design. Look into aspects of design from variables to samples.

Next, in our lessons, learn about validity and reliability. We will introduce you to the process of assessing the quality of a research study. You will discover the correct way to interpret correlations in research results and jump into a discussion on why correlation doesn't imply causation. Get a crash course in the use of statistics for psychology studies. After viewing our lessons, you'll understand basic statistical concepts and be able to show them on a bell curve. You will also understand how to interpret bell curves and gain an understanding of inferential statistics and how to interpret p-value.

Ethics are always a factor in research. So you will need to gain an understanding of how ethics apply in an educational psychology setting. Our lessons lead you into a discussion of basic ethical expectations for research studies that involve human participants. Get familiar with things like consent forms and debriefing procedures. Before you know it, you will be all prepared to conduct a research study involving humans. Armed with the knowledge of research ethics, you can aim to ensure that your study will be conducted in a professional and legal manner. Thanks for watching!
