IAL Edexcel Statistics 1
This GeoGebra companion maps directly to all chapters of the Pearson Edexcel International A-Level Statistics 1 Student Book. Each chapter contains short, interactive investigations that mirror the textbook topics so students can explore data sets, visualise distributions, test probability models, and understand statistical concepts dynamically.
- Measures of Location and Spread — mean, median, and mode calculators that update in real-time with data changes, standard deviation and variance visualisers, and explorers for the effects of coding.
- Representation of Data — interactive histogram and stem-and-leaf builders, dynamic box plot and outlier visualisers, and cumulative frequency graph drawers.
- Correlation and Regression — dynamic scatter plot graphers with movable data points, real-time calculation of the PMCC, and an interactive least-squares regression line that updates as points are added or moved.
- Probability — interactive Venn diagram shaders for 2 and 3 sets, dynamic tree diagram builders, and simulators for conditional probability and independence.
- Discrete Random Variables — custom probability distribution builders, visual calculators for E(X) and Var(X), and interactive models for the discrete uniform distribution.
- The Normal Distribution — a fully interactive normal curve with dynamic sliders for mean and variance, standardisation (Z-value) visualisers, and real-time probability area calculators.
