Introduction to Statistical Investigations, Second Edition provides a
unified framework for explaining variation across study designs and
variable types, helping students increase their statistical literacy and
appreciate the indispensable role of statistics in scientific research.
Requiring only basic algebra as a prerequisite, the program uses the
immersive, simulation-based inference approach for which the author team
is known. Students engage with various aspects of data collection and
analysis using real data and clear explanations designed to strengthen
multivariable understanding and reinforce concepts.
Each chapter follows a coherent six-step statistical exploration and
investigation method (ask a research question, design a study, explore
the data, draw inferences, formulate conclusions, and look back and
ahead) enabling students to assess a variety of concepts in a single
assignment. Challenging questions based on research articles strengthen
critical reading skills, fully worked examples demonstrate essential
concepts and methods, and engaging visualizations illustrate key themes
of explained variation. The end-of-chapter investigations expose
students to various applications of statistics in the real world using
real data from popular culture and published research studies in variety
of disciplines. Accompanying examples throughout the text, user-friendly
applets enable students to conduct the simulations and analyses covered
in the book.
