Schools & departments: shared access, consistent planning

Give multiple teachers access to the same ready-to-teach resources, support consistent lesson sequencing across classes and reduce duplicated planning across the department. School membership is ideal for teams who want shared access to lessons, worksheets and practice across KS3, GCSE, IGCSE and A-Level.

Representing Data: GCSE / IGCSE

These GCSE / IGCSE representing data lessons consolidate core charts and extend to grouped data, cumulative frequency, box plots, time series and histograms. Topics include:

  • Stem-and-leaf diagrams: reading data and calculating averages from a stem-and-leaf display
  • Bar charts from tally tables and raw data; pictograms from tally and frequency tables
  • Pie charts: drawing from frequency tables and interpreting pie charts using proportions and angles
  • Cumulative frequency graphs from grouped data, including estimating the median
  • Frequency diagrams and frequency polygons for grouped data
  • Time series: plotting data over time and recognising trends
  • Box-and-whisker diagrams for comparing distributions
  • Histograms with unequal class widths using frequency density, including drawing and interpreting histograms to estimate the mean

Representing Data: A-Level

These A-Level statistics lessons revisit key representations with a focus on interpretation, estimation and outlier detection linked to quartiles. Topics include:

  • Box plots and outliers, including identifying outliers using rules based on the interquartile range
  • Cumulative frequency: plotting and interpreting cumulative frequency graphs, estimating medians and quartiles, and linking to box plots
  • Histograms: plotting and interpreting histograms using frequency density, including probability estimates from histograms
