# Box and Whisker Diagrams

Students learn how to compare sets of data using box and whisker diagrams to measure the interquartile range and median average.  As learning progresses cumulative frequency diagrams are used to create box plots.  This lesson comes with a worksheet to practise drawing box plots and another to practise drawing them from grouped data.
##### Differentiated Learning Objectives
• All students should be able to calculate the median from a Box and Whisker Diagram to comment on a distribution.
• Most students should be able to calculate the median and IQR from a Box and Whisker Diagram to comment on a distribution.
• Some students should be able to compare multiple distributions using the Median and IQG from a Box and Whisker diagram.

#### How to Draw a Venn Diagram to Calculate Probabilities

There are three common ways to organise data that fall into multiple sets: two-way tables, frequency diagrams and Venn diagrams.  Having blogged about frequency diagrams before I thought I would write about how to draw a Venn Diagram to calculate probabilities. Recapping Two-Way Tables This activity works well to review two-way tables from the previous […]

#### Calculations with Percentages

Students learn how to find a percentage of an amount using calculator and non-calculator methods.  As learning progresses they use decimal multipliers to find a percentage change and calculate a simple interest in financial mathematics. This topic follows on from Fractions, Decimals and Percentages and takes place in Year 8 Term 5. Calculations with Percentages […]
