This lesson… We are going to review how to analyse data
using a frequency table.
To succeed: you will know how to find the mean and mode from a grouped frequency table.
To excel: you will know how to find the class that contains the median from a grouped frequency table.
Challenge: to use a frequency table to present the data in a cumulative frequency diagram.

…and how exciting! It’s our 20-year 11S-Ma2 class reunion!

Many of you have careers, spouses and children- which means a lot of data for me!

Being the extremely cool mathematician that I am I decide to analyse some of this data.
First, I want to find out the average number of children that my students have had.

Next, I would like to find out the average age of the children.

What makes analysing this data more difficult?

Try it! Each of you has a number 1-3.
You must group yourself so you have 1 of each number.
Together, try and answer the exam question on finding averages from a frequency table.
