Averages and Frequency Tables

I'm going to use this in the coming couple of weeks with my Year 9 and 10 classes.  I hope it explains finding averages from frequency tables quite well.

Please do make any suggestions for improvement, variations that could be made, and let me know of any errors in the resources, or sections that students find confusing.
