By the end of the lesson I would hope that you have an understanding and be able to apply to questions the following concepts: Understand why we would need to have methods to display numerical data. Understand what a grouped frequency distribution is and how to create one. Understand what a histogram is and how to create one (both by hand and using your CAS) from a frequency table and from raw data. Know what to look for in a histogram in terms of Shape, Outliers, Centre and Spread. Also, know what Range is; how to find it and why it's not always the best thing to use.
