Frequency table worksheet for GCSE and iGCSE maths: averages from a table, modal class and estimating the mean of grouped data. With full worked solutions.

A complete frequency tables worksheet for Pearson Edexcel GCSE (1MA1) and International GCSE (4MA1), written so one resource works for both tiers. Every section is clearly labelled Foundation or Higher, and questions get harder as you go.

What’s covered — Foundation

Making a frequency table from a list
Finding the mode, median, mean and range from a frequency table
Finding the modal class and the class containing the median
Estimating the mean of grouped data using midpoints

What’s covered — Higher (grades 6 to 9)

Quartiles from a table
Estimating within a class
Finding missing frequencies

How it’s structured

A. Worked examples & Your turn — a model solution beside a matching question to try
B. Fluency — core skills
C. Reasoning — explain it
D. Problem solving — unfamiliar, multi-step questions
E. Exam practice — exam-style questions with mark allocations

123 marks across Sections B to E (61 Foundation, 62 Higher), with a progress tracker on the front page so students can record their score per section. The word “estimate” is treated as load-bearing: students are repeatedly asked why a grouped mean can only ever be an estimate.

How to use it

Works as a full lesson, homework, a cover lesson or targeted intervention. Because each tier is labelled, you can set the Foundation sections to one group and the Higher sections to another from the same print.
