Basic Statistics

In this lecture I will introduce the concepts of measures of central tendency (mean, median & mode) and of dispersal (standard deviation). I will also talk about histograms.

The second part of the lecture will cover a brief introduction to the ethics of testing. I will hand out copies of the form for excemption, and my own protocols.
