Monty the Null Hippopotamus

Exploring Statistical Foundations Through Simulation

A revolutionary approach to introductory statistics for students who grew up in the computing age. Breaking away from the traditional formula-memorization approach that makes "Stat 101" a dreaded requirement, Monty emphasizes computational thinking and conceptual understanding through hands-on coding examples. The aim is to make statistics accessible and engaging by leveraging modern computing power rather the tedium of punching numbers into calculators or flipping through pages of tables.

Topics/features include:

  • Foundational statistical concepts: binomial, location/Gaussain models, ANOVA, correlation
  • Advanced topics: nonparametric methods and regression
  • Emphasizes simulation and Monte Carlo methods over formula memorization.
  • Everything illustrated with fully reproducible code.
  • Graduated homework exercises combining theory with real-world data analysis.
  • More than thirty data sets supporting examples and exercises.
  • Favors understanding over pedantry, with extensive web links and contextual references.

Designed for undergraduates comfortable with probability, calculus, and basic programming. Serves as an ideal text for introductory statistics courses. Equally valuable for graduate students from non-statistical backgrounds seeking a modern foundation in statistical thinking. Perfect for students who are ready to engage deeply with statistical concepts through hands-on exploration.

Merch

Like Dave's Hipp0 or want to support the book but don't need a paper copy?

  • Consider some merch.
  • Prices set so about $10 comes to me and Dave, and the rest to Printful.
  • That's similar to buying a hardcover copy.
  • If Printful has something you like in their catalog that is not in our store, let us know and we'll consider adding it.
