Statistics

We will revise statistics for the next few classes.
The main skills you need for this question are:
- being able to work with frequency distributions in their various forms
- being able to calculate standard deviations
- being able to graph data using histograms and ogives
- being able to interpret graphs ( remember to show the markings that indicate how you work out e.g. median or mean from your graphs)

We will go over the topics that came up in the 2007 paper in class tomorrow.

Here is the 1-page overview for statistics.
