This is another video is the General Maths series for Year 11 dealing with comparing the distribution of a numerical variable across two or more. Statistics is about comparing data. We can use stem plots and parallel box plots to help us describe the trends in categorical and numerical data. Shape, centre, spread and outliers are all things which these wonderful diagrams can help us identify and compare. I use a number of worked examples to explain how to get the most marks in a statistical investigation. All delivered in my own unique style!
