This version isn't the most recent version of the book. We recommend the Second Edition at https://moderndive.com/v2/, which was finalized in Fall 2024 to be published as a hard copy in early 2025 by CRC Press. You can find a summary of the updates in the Second Edition here.

Foreword

These are exciting times in statistics and data science education. (I am predicting this statement will continue to be true regardless of whether you are reading this foreword in 2020 or 2050.) But (isn’t there always a but?), as a statistics educator, it can also feel a bit overwhelming to stay on top of all the new statistical, technological, and pedagogical innovations. I find myself constantly asking, “Am I teaching my students the correct content, with the relevant software, and in the most effective way?” Before I make all of us feel lost at sea, let me point out how great a life raft I have found in ModernDive. In a sea of intro stats textbooks, ModernDive floats to the top of my list, and let me tell you why. (Note my use of ModernDive here refers to the book in its shortened title version. This also matches up nicely with the neat hex sticker Drs. Ismay and Kim created for the cover of ModernDive, too.)

My favorite aspect of ModernDive, if I must pick a favorite, is that students gain experience with the whole data analysis pipeline (see Figure 0.2). In particular, ModernDive is one of the few intro stats textbooks that teaches students how to wrangle data. And, while data cleaning may not be as groovy as model building, it’s often a prerequisite step! The world is full of messy data and ModernDive equips students to transform their data via the dplyr package.

Speaking of dplyr, students of ModernDive are exposed to the tidyverse suite of R packages. Designed with a common structure, tidyverse functions are written to be easy to learn and use. And, since most intro stats students are programming newbies, ModernDive carefully walks the students through each new function it presents and provides frequent reinforcement through the many Learning checks dispersed throughout the chapters.

Overall, ModernDive includes wise choices for the placement of topics. Starting with data visualization, ModernDive gets students building ggplot2 graphs early on and then continues to reinforce important concepts graphically throughout the book. After moving through data wrangling and data importing, modeling plays a prominent role, with two chapters devoted to building regression models and a later chapter on inference for regression. Lastly, statistical inference is presented through a computational lens with calculations done via the infer package.

I first met Drs. Ismay and Kim while attending their workshop at the 2017 US Conference on Teaching Statistics. They pushed us as participants to put data first and to use computers, instead of math, as the engine for statistical inference. That experience helped me modernize my own intro stats course and introduced me to two really forward-thinking statistics and data science educators. It has been exciting to see ModernDive develop and grow into such a wonderful, timely textbook. I hope you have decided to dive on in!
