I am not a trained statistician, but I have a natural propensity for understanding the world through data. Guided by the belief that the best way to learn is to teach, I began teaching introductory statistics courses several years ago. This journey has taught me that visual explanations are often the most powerful way to deepen our grasp of applied statistical concepts. To support this approach, I have designed an interactive toolkit that provides students and returning learners with real-time visual feedback as they explore the following topics hands-on.
Charts (vertical bars, horizontal bars, lollipop, Pareto, word clouds, grouped bars, line, nested bubbles, mirrored charts, pie, doughnut, treemap, sunburst, stacked bars, 100% stack bars, streamgraphs, Venn, Venn + Euler hybrid, UpSet, heatmap, alluvial, and Sankey)
Histogram and density (with normality test and visual diagnostics)
Quartiles and boundaries
Scatter plots
Grouped scatter plots
k-means clustering
Probability distributions
Central Limit Theorem (CLT) demo
Confidence Intervals (CI) demo
CI estimation
Resampling
One and two-sample hypothesis tests
Chi-square tests (goodness-of-fit and test of independence)
Simple linear regressionÂ
Multiple linear regression (with numerical, categorical, and interaction term modelling), including model diagnostics and plots
Comparing two groups (means and proportions)
ANOVA - comparing three or more groups (One-way ANOVA and two-way ANOVA: RCBD, factorial, mixed-design)
Binary logistic regression
Ordinal logistic regression
Visualise growth
Projections
