Synopsis
This manual offers a clear, accessible, and practical guide to the study of descriptive statistics, specifically designed for high school and college students. Through a progressive structure and realistic examples, the book introduces the fundamental concepts of statistics: data types, table organization, measures of central tendency, dispersion, and position, for both ungrouped and grouped data. In addition to the theoretical content, it includes step-by-step exercises that allow the reader to develop practical skills and understand the real-world use of statistics in contexts such as health, the environment, production, and education. The pedagogical approach seeks to debunk myths about the difficulty of the subject and promote a critical and meaningful understanding of data. As an added value, the book includes an introduction to the use of the free JASP software, allowing readers to transfer what they have learned to the digital environment, strengthening their statistical and digital literacy. More than a technical manual, this work is a training tool that combines clarity, usefulness, and support, inviting the reader to discover that statistics is not just about numbers, but a powerful way to understand and transform the world.
