Statistics Video Presentations

The videos and lessons below use graphical procedures and data summary statistics. Any further statistical procedures used are listed below individually.
Most methods are in the New Zealand high school curriculum but others (for example multiple linear regression and multivariate procedures) are more appropriate at university undergraduate level.
Videos 1 through 13 include exercises that can be carried out with the program GenStat.
