This is a FIVE lesson bundle on averages from grouped and non grouped data as well as an excellent lesson on moving averages. This is an area that is done poorly by students particularly estimated mean, so it is worth teaching this thoroughly, which this bundle does.
1. Basic Averages (mode, median, mean) and the Range
2. What average is best (rich task)
3. Grouped Data - Finding the estimated mean
4. Grouped vs Non Grouped data (practical lesson)
5. Moving Averages
