Statistical Diagrams are a key part of Mathematics; data is regularly presented to us in newspapers, magazines and on the Internet. Students can get confused between the different statistical diagrams, what is needed for each, how to draw them and how to interpret information from them. The resources below will challenge your students and help them to remember the concepts better.

#### Top 10 Resources:

Data analysis tool

• This is a truly amazing resource that has a set of teacher’s notes to accompany it. The Excel spread sheet automatically creates frequency tables, frequency polygons, histograms, cumulative frequency diagrams, box plots, mean and standard deviation based on a set of data of your choice. A great way to discuss the various ways of representing the same data.

Histogram Cut-up

• This is a really good, challenging resource that explores histograms, frequency density and even skewness. This would be particularly useful for G&T students in Year 9 or for Higher Tier GCSE classes.

S5 Interpreting bar charts, pie charts, box and whisker plots

• A really useful activity from the DfE Standards Unit on exploring the relationships between bar charts, pie charts and box and whisker plots. The activity includes a card match activity comparing the 3 different statistical diagrams.

S6 Interpreting frequency graphs, cumulative frequency

• This resource comes again from the DfE Standards Unit and leads on from the previous resource. This time the resource explores frequency graphs, cumulative frequency graphs and box and whisker plots.

Drawing Statistical Graphs on Autograph

• A great resource that provides students (and teachers) with a step-by-step guide to using Autograph to create histograms, cumulative frequency graphs and box and whisker plots from a grouped frequency table.

Stem and Leaf Diagrams Worksheet

• A brilliantly differentiated set of worksheets to help students draw and interpret stem and leaf diagrams. The worksheets are split into different sections, each with a set of smiley faces to assess their understanding of the section.

Super Hero Top Trumps – Scatter graphs lesson

• This engaging resource looks at the different attributes of Super Heroes and asks students to work out the correlation of the attributes against one another. It also gets students to work out the averages of different data, allows students to create their own top trumps cards and provides an extensive amount of data to use in class.

Cumulative Frequency

• This resource is a complete lesson plan with starter activities, examples, mini plenaries, instructions and a final plenary. The PowerPoint is completed with teacher’s notes and is very clear.

Funny Pie Charts

• A truly engaging activity to introduce pie charts to students. The resource would be best used with Year 7 as a starter activity into Pie charts before going on to getting the students to interpret/draw their own pie charts from a given set of data.

Venn Diagram & HCF/LCM Starter

• An engaging little starter for introducing Venn Diagrams to classes. Using the information on the slides the students use a Venn Diagram to compare either Superman and Batman or Shrek and Donkey. This resource can also be used as a starter to teaching HCF and LCM.
