Three worksheets on finding the mean, the mode, the median, the quartiles and interquartile range of a given set. Detailed solutions are provided.

Master data analysis and averages with this comprehensive 3-worksheet statistics practice bundle. Perfectly aligned with the UK National Curriculum for KS3 and KS4 (Years 7–11), this differentiated maths pack confidently guides students from basic averages to advanced quartiles and interquartile range (IQR).

Are you looking for a high-quality, time-saving resource to teach, reinforce, or review averages and measures of spread?
This complete statistics practice bundle is sequentially designed to build student confidence, mathematical fluency, and absolute mastery over data distribution. Featuring three extensive worksheets with a clear progression of difficulty, this resource makes classroom differentiation effortless for secondary school maths teachers working with mixed-ability groups.

What is Included in This Bumper Pack?
This download contains three separate practice packs, structured progressively to scaffold learning:
• Worksheet 1 (Calculating the Mean): Focuses on finding the mean from diverse datasets, moving from whole numbers to decimals. It also includes multi-step worded problems, reverse mean calculations (finding the sum or a missing value), and combined mean problems.
• Worksheet 2 (Mean, Median, and Mode): Combines all three measures of central tendency into comprehensive datasets. This sheet stretches algebraic and statistical fluency by incorporating negative numbers, decimals, and datasets with multiple modes or no mode at all.
• Worksheet 3 (Quartiles & Interquartile Range): Explores measures of spread by requiring students to find the lower quartile (Q1), median (Q2), upper quartile (Q3), and the overall interquartile range (IQR). Problems cover odd and even numbered lists, negative datasets, and decimal arrays.
• Full Teacher Solutions: Complete, step-by-step written answers are provided for every single question across all three worksheets to support quick peer-marking, student self-assessment, or to save you valuable grading time.

Versatile Classroom Applications
This versatile bundle is highly adaptable and can be seamlessly integrated into your maths planning as:
• Structured homework assignments to consolidate weekly learning.
• Independent main-lesson practice during statistics and data handling units.
• Target math intervention, catch-up work, or small-group revision sessions.
• Cover lessons, low-stakes quizzes, or end-of-term GCSE exam preparation.

National Curriculum Alignment
This resource perfectly covers the fluency and reasoning proficiency requirements for Key Stage 3 and Key Stage 4 Mathematics, matching core data objectives within the GCSE Foundation and Higher specifications (AQA, Edexcel, and OCR modules):
• KS3/KS4 Maths: Describe, interpret, and compare distributions of a single variable through appropriate measures of central tendency (mean, median, mode) and spread (range, quartiles, and interquartile range).
