Synopsis

Explore how statistics measures groups and trends with clear, practical methods.

This collection presents Bowley’s lectures on the measurement of groups and series, drawn from early 20th‑century actuarial and statistical practice. It covers fundamental ideas, from how to compare groups to the practical use of graphic and mathematical tools, with a focus on real data and careful interpretation.

The book introduces core techniques, explains their assumptions, and shows how they apply to problems like census data, incomes, wages, and age distributions. It emphasizes choosing group sizes wisely, distinguishing exact observations from samples, and interpreting results with an eye for precision and reliability. The material blends theory with hands‑on examples, aiming to equip readers to analyze variability and relationships in data.

• Graphic representation of data, including diagrams and dot plots that illustrate distributions
• Methods of describing groups through averages, variability measures, and the curve of error
• The method of least squares and how to fit models to observations
• How to assess correlation between two series and interpret results visually and mathematically

Ideal for students and professionals who want a solid, historical approach to statistical measurement, estimation, and inference.

Ideal for readers of early statistical texts and practitioners seeking foundational methods that still inform modern data analysis.
