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.
