Experimental Designs

Experimental design plays a critical role in producing reliable, evidence-based research across academic and professional fields. This course explores the foundations of experimental design, including randomisation, control methods, trials, and ethical considerations, helping learners understand how to create valid and trustworthy research studies. Through structured explanations and practical examples, learners will gain insight into the importance of causal inference and rigorous experimentation. The course guides learners through the process of planning, executing, and evaluating experimental studies using both foundational and advanced approaches. Learners will explore pre-experimental, true experimental, and quasi-experimental methods while developing the skills needed to improve research quality, minimise bias, and strengthen validity in professional research settings. What makes this course unique is its balanced approach between theoretical understanding and practical implementation. Alongside core experimental concepts, learners will examine real-world research scenarios and reporting practices, enabling them to apply experimental methods effectively across diverse disciplines. This course is ideal for researchers, students, analysts, and professionals in psychology, healthcare, economics, education, and social sciences. A basic understanding of research methods is helpful, but the course supports both introductory and advanced learners seeking to strengthen their research design expertise. This course is based on the book Experimental Designs by Barak Ariel, Matthew Bland, and Alex Sutherland. Copyright ©2021 by Sage Publications Limited.
