These videos and lessons use graphical methods and data summary statistics. Further statistical procedures are listed with each case study. Data are available in Excel format for anyone wishing to try some of the analyses but graphical procedures along with video discussion usually lead to the main results.
Most methods are in the New Zealand high school curriculum or first year University. Others (for example multiple linear regression and multivariate procedures) are more appropriate at 200+ University undergraduate level.
Videos 1 through 13 include exercises that are designed with GenStat, but be carried out with any statistical package.
