Bracketology Club: Using March Madness to Learn Data Science with Brian Tonsoni

12m 7s • COURSE
When one pictures the group who bested over 100 sports experts to win the 2016 Bracket Matrix—an online March Madness bracket competition—a classroom full of small-town high school students might not be the first image that comes to mind. It certainly wasn't what social studies teacher Brian Tonsoni expected when started Delphi Bracketology—a high school club that uses data science to predict which teams the NCAA will select for the Division I Men's Basketball Tournament. But what began as an informal gathering of sports fans soon grew into a collection of champions. In this short film, meet some of the members of this remarkable team, and learn how Tonsoni's informal, project-based approach to learning helped these young bracketologists acquire the kinds of key skills—data science, public speaking, and more—that every teacher hopes to instill in their students.

Data Science Foundations: Fundamentals with Barton Poulson

3h 6m • COURSE
Introduction to Data Science provides a comprehensive overview of modern data science: the practice of obtaining, exploring, modeling, and interpreting data. While most only think of the "big subject," big data, there are many more fields and concepts to explore. Here Barton Poulson explores disciplines such as programming, statistics, mathematics, machine learning, data analysis, visualization, and (yes) big data. He explains why data scientists are now in such demand, and the skills required to succeed in different jobs. He shows how to obtain data from legitimate open-source repositories via web APIs and page scraping, and introduces specific technologies (R, Python, and SQL) and techniques (support vector machines and random forests) for analysis. By the end of the course, you should better understand data science's role in making meaningful insights from the complex and large sets of data all around us.
Topics include:
  • Assess the skills required for a career in data science.
  • Evaluate different sources of data, including metrics and APIs.
  • Explore data through graphs and statistics.
  • Discover how data scientists use programming languages such as R, Python, and SQL.

Statistics Foundations: 1 with Eddie Davila

2h 6m • COURSE
Statistics is not just the realm of data scientists. All types of jobs use statistics. Statistics are important for making decisions, new discoveries, investments, and predictions. Whether the subject is political races, sports rankings, shopping trends, or healthcare advancements, statistics is an instrument for understanding your favorite topic at a deeper level. With these beginner-level lessons, you too can master the terms, formulas, and techniques needed to perform the most common types of statistics.

Professor Eddie Davila covers statistics basics, like calculating averages, medians, modes, and standard deviations. He shows how to use probability and distribution curves to inform decisions, and how to detect false positives and misleading data. Each concept is covered in simple language, with detailed examples that show how statistics are used in real-world scenarios from the worlds of business, sports, education, entertainment, and more. These techniques will help you understand your data, prove theories, and save time, money, and other valuable resources—all by understanding the numbers.
Topics include:
  • Why statistics matter
  • Evaluating your data sets
  • Finding means, medians, and modes
  • Calculating standard deviation
  • Measuring distribution and relative position
  • Understanding probability and multiple-event probability
  • Describing permutations: the order of things
  • Calculating discrete and continuous probability distributions
