A lecture on scattergrams (scatterplots) and correlation in quantitative research by Graham R Gibbs taken from a series on quantitative data analysis and statistics given to undergraduate students at the University of Huddersfield. This is part 3 of 3 and examines when to use parametric tests of correlation such as Pearson r and when to use non-parametric equivalents such as Kendal's tau and Spearman's rho.
