Intermediate Statistical Investigations 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
a single introductory statistics course 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 examples and clear explanations
designed to strengthen multivariable understanding and reinforce
first-course concepts.
Each chapter contains in-depth exercises which follow a consistent
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.
End-of-chapter investigations use real data from popular culture and
published research studies in a variety of disciplines, exposing
students to various applications of statistics in the real world.
Throughout the text, user-friendly Rossman Chance web applets allow
students to conduct the simulations and analyses covered in the book.
