Quality of quantitative research

The video explores the concepts of reliability and validity in the context of quantitative research. Reliability refers to the consistency of results when a study is repeated under the same conditions, while validity pertains to whether the study accurately answers the research question. The video breaks down validity into four categories: measurement validity, statistical conclusion validity, internal validity, and external validity.

The video emphasizes the importance of research design in determining the quality of a study. It highlights that the research process starts with formulating a research question, followed by preparing the research design, which includes sampling and measurement. Data collection comes next, and once the data is collected, it sets the upper limit of the study's quality. The video asserts that even if mistakes are made during data collection, analysis, or interpretation, they can be corrected if the data is good. However, a poorly designed study cannot be salvaged by complex data analysis methods. The quality of a study is largely determined before data collection and a well-designed study is more important than a fancy method.
