A lecture by Graham R Gibbs taken from a series on quantitative data analysis and statistics given to undergraduate students at the University of Huddersfield. Part 1 examines when to use the independent samples t-test and when to use its non-parametric equivalent, the Mann-Whitney U test. Part 2 examines the analysis of variance (ANOVA) and how to interpret the results of an ANOVA. This playlist also includes two other short videos from YouTube on the Mann Whitney test and on One-way ANOVA.
