In this video, I provide an introduction to hypothesis testing in psychology. Hypothesis testing is an essential statistical tool used in psychological research to determine whether a hypothesis about a population is true or false. We explain the steps involved in hypothesis testing, including defining the null and alternative hypotheses, selecting an appropriate statistical test, calculating the test statistic, determining the p-value, and interpreting the results. We also provide examples of hypothesis testing in psychological research, such as testing the efficacy of a new therapy or determining if a group of participants performed better than chance on a task. Whether you're a psychology student or researcher, this video will give you a clear understanding of how hypothesis testing is used in psychological research and how to interpret the results of your experiments.
This is lecture 8 by Eric Vanman for PSYC1040 at the University of Queensland.
