Discussion of Sample Displays When describing dot plots: discuss symmetry, skew, outliers, gaps, clusters Box and whisker: Summary statistics, symmetry, skew It there are sub groups or a second variable using different colours to show this, and discuss as well. “In my sample...” The discussion needs be in context at all levels. The context includes the variable, for example height, numerical values and associated units and the population groups. 
Activity: Box plot discussing Quiz on Distribution Sample Shapes.pdf (link to Census at schools) Worksheet and answers on 'What I notice about a distribution' (link to mathstatsfacilitators web site) 
Dot plotsSymmetry  Is the data symmetrical either side of the median? Or is one side more spread out? Skew  Data spreading right is right skewed Outliers 
Any data more than 1.5 ‘boxes’ above UQ is an outlier. Data more than 3 ‘boxes’ above UQ is extreme (see later notes) Clusters  A bunching of data in one region

Box PlotsWhen describing Box and whisker: Summary statistics, centrality, spread, symmetry, skew, tail length Summary statistics (Review) – do not discuss Max or Min (irrelevant) Discuss the ‘middle 50%’ ie the ‘box’ and median If comparing samples discuss overlap and shift (eg distance between medians) Show groups or a second variable using a different group colour. Discuss these groupings Discussion And for merit things like: ‘I notice ... I expected ... I was surprised that...’
