This was our first class since last Wednesday. We started class deciding on a revision plan. We will spend one more day on Statistics and then spend that last 8 or so classes revising our years work. Today we focused on terms: Mean, Mode, Median and Standard deviation. In particular we practiced using the Casio calculator to find the mean and standard deviation of a frequency distribution table. Resources to help with this are uploaded in this blog. HW  to see if you can use that calculator to get the answers to the sample questions on p.72f.
