This GeoGebra companion maps directly to all chapters of the [b]Pearson Edexcel International A-Level Statistics 1 Student Book[/b]. 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.
[list]
[*][b]Measures of Location and Spread[/b] — 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.
[*][b]Representation of Data [/b]— interactive histogram and stem-and-leaf builders, dynamic box plot and outlier visualisers, and cumulative frequency graph drawers.
[*][b]Correlation and Regression[/b] — 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.
[*][b]Probability[/b] — interactive Venn diagram shaders for 2 and 3 sets, dynamic tree diagram builders, and simulators for conditional probability and independence.
[*][b]Discrete Random Variables [/b]— custom probability distribution builders, visual calculators for E(X) and Var(X), and interactive models for the discrete uniform distribution.
[*][b]The Normal Distribution [/b]— a fully interactive normal curve with dynamic sliders for mean and variance, standardisation (Z-value) visualisers, and real-time probability area calculators.
