About the Course
In this course, Dr Alison Wadeley (Bath Spa University) explores the challenging subject of inferential statistics. In the first module, we think about the decision tree required to establish which non-parametric test should be used, based on the experimental design and the data being collected. In the second module, we think about four example research questions and work through the process of deciding which non-parametric test is appropriate for each, before moving on to parametric tests. In the third module, we think about how the sign test is used to assess a research question on sleep quality and social media use. Next, we think about probability, critical values, and significance; helping to unpack the inner workings of these tests. In the fifth and final module, we think about the errors that can occur when interpreting results from these tests, how you might recognise them, and what can be done to reduce their prevalence.
