Yesterday we covered finding averages from frequency tables, and also revised some of the key facts about cumulative frequency tables.
Your first task was to match up the correct frequency table with the cumulative frequency graph using this document (p3).
We then had a quick recap of finding averages from frequency tables, before you completed an activity matching bar charts to their key statistics. You found it challenging to fill in the missing statistics, and to complete the blank graph with the statistics provided, but you all completed it – well done! See here for the activity (see last two pages).
Finally, you were given a histogram (Lesson Ideas – Histograms – page 2) for which you had to construct the grouped frequency table and find the averages – you managed to complete this to a high standard using excellent team work – well done!
Homework was to complete Exercise 2C, due Tuesday. Those of you who missed the lesson need to catch up. We only have one more lesson left on this topic.
Have a lovely weekend,
