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.
