11+ Statistics & Data Handling
11+ Statistics & Data Handling Workbook
 
Master the data skills that appear on every 11+ paper. This 16-page workbook takes your child from confidently reading their first bar chart to solving the multi-step statistics problems favoured by GL Assessment, CEM, QUEST and independent school examiners.
Inside, your child will work through 50 carefully sequenced questions covering bar charts and dual bar charts, pie charts (fractions, percentages and sector angles), and all four averages — mean, median, mode and range — including the reverse-mean problems that catch so many candidates out.
 
Every topic opens with a clear worked example, then builds through three difficulty levels: Foundation (★), Intermediate (★★) and Advanced (★★★). Custom-drawn charts, dedicated working space, section score boxes and a complete answer key with full worked solutions make it ideal for independent practice at home or alongside tuition.
  • 50 practice questions across 4 sections
  • 8 custom charts and graphs to interpret
  • Worked examples for every topic
  • Tiered difficulty: Foundation, Intermediate, Advanced
  • Full answer key with step-by-step solutions
