IGCSE Maths: Statistics & Probability

Overview

Statistics and Probability covers data collection, representation, and analysis. Core students work with basic averages and simple probability, while Extended students tackle cumulative frequency, histograms with unequal intervals, and conditional probability.

Core Syllabus Topics

• Mean, median, mode, range
• Bar charts and pie charts
• Pictograms and frequency tables
• Simple probability
• Probability from experiments

Extended Syllabus Topics

• Cumulative frequency curves
• Box-and-whisker plots
• Histograms (unequal class widths)
• Standard deviation (interpretation)
• Tree diagrams
• Conditional probability
• Venn diagram probability

Common Mistakes to Avoid

• Using frequency instead of frequency density for histograms
• Forgetting 'without replacement' changes probabilities
• Misreading cumulative frequency graphs
• Confusing independent and mutually exclusive events
