  • Data scraping, ingestation, and modeling: bringing data from cars.com into the intro stats class

    Nicholas Horton, Amherst College
    Tuesday, November 21, 2017 - 2:00pm
    In this webinar, I will describe a classroom activity where pairs of students hand scrape data from cars.com, ingest these data into R, then carry out analyses of the relationships between price, mileage, and model year for a selected type of car. This early in the semester activity can help illustrate the statistical problem solving process. The "Less Volume, More Creativity" approach utilized by the mosaic package facilitates the analysis with a minimal amount of syntax. Key concepts that are introduced and reinforced including data ingestion, multivariate thinking through graphical visualizations, and regression modeling. Extensions and additional use of the dataset will be discussed along with potential pitfalls. Project Files: https://github.com/Amherst-Statistics/Cars-Scraping-Webinar
  • Regression to the Mean/The regression effect

    Jeff Witmer (Oberlin College)
    Tuesday, October 17, 2017 - 2:00pm
    Regression to the mean, also known as "the regression effect," is an important but sometimes overlooked topic in introductory statistics. We will discuss the regression effect and how to teach it. We will also consider a number of examples of the "regression fallacy," in which people who are ignorant of the regression effect make up ad hoc (and sometimes very misleading) explanations for what they see in data.
  • Maximizing Linked Data's Network Effect

    Carolee Mitchell, Academic Relationships Manager, data.world
    Tuesday, July 25, 2017 - 2:00pm
    18M+ open datasets exist today, and growth is accelerating. But these data sets live in data portals without common taxonomies or architectures, and must first be cleaned and prepared by data users. Human and computers normalize, extract meaning, and identify correlations, but this work is siloed: used for one project, then lost forever, only to be repeated from scratch by the next person to touch the data. Open data can help us rise to humanity’s toughest challenges, but only if we maximize its network effect. To build the web of Linked Data, we have to start by connecting the people who are working with data. Visit: https://data.world/
  • Teaching the Past, Present, and Future of Statistics

    Nicholas J. Horton (Amherst College)
    Tuesday, June 20, 2017 - 2:00pm
    In 2014 Committee of Presidents of Statistical Societies (COPSS) published a book entitled "Past, Present, and Future of Statistical Science" that contains 52 short chapters contributed by past winners of one of the COPSS Awards. The goal of the book (which is freely downloadable from the COPSS website or http://tinyurl.com/copss-ppf) was to "showcase the breadth and vibrancy of statistics, to describe current challenges and new opportunities, to highlight the exciting future of statistical science, and to provide guidance for future generations of statisticians (page xvii)." In this webinar, I will describe how these chapters were integrated into a theoretical statistics course to help students see the big picture and potential for statistics.
  • Initial Findings about Graduate Teaching Assistants’ Training Needs to Foster Active Learning in Statistics

    Kristen Roland and Jennifer Kaplan (University of Georgia)
    Tuesday, April 18, 2017 - 2:00pm
    As enrollment in introductory statistics courses across the country rises, more instructors for these courses are needed. Many statistics courses are now taught by Graduate Teaching Assistants (GTAs). Little is known, however, about the training needs of GTAs to foster active learning and promote conceptual understanding, critical recommendations of the GAISE guidelines to improve undergraduate learning in statistics. This talk will discuss changes to our lab activities to incorporate GAISE recommendations of teaching for conceptual understanding, foster active learning, and integrating real data. We will also discuss initial findings concerning the struggles GTAs have with connecting their theoretical knowledge to conceptual ideas concerning confidence intervals for one population proportion. The material is based on work supported by NSF DUE 1504587.
  • A Fully Customizable Textbook for Introductory Statistics/Data Science Courses

    Chester Ismay and Albert Y. Kim
    Tuesday, March 14, 2017 - 2:00pm
    This webinar will provide a guide to creating a user-adaptable electronic textbook incorporating data visualization, data science, and other relevant pedagogical concepts into your introductory statistics course. We present our own introductory statistics and data science textbook available at http://moderndive.com that: Focuses on the entirety of the data/science pipeline from importing data to visualizing and summarizing data to inferential techniques and developing students as effective data storytellers Blurs the line between lecture and lab Uses freely available modern, rich, and complex data sources Leverages resampling and simulation to build statistical inference concepts Most importantly, provides complete customizability to the instructor and reproducibility to the student We’ll discuss how collaboration and crowd-sourcing have and will play a role in our textbook going forward and other open-source materials we are creating to better support introductory statistics/data science students learning the skills and tools that statisticians/data scientists are using today.

  • A Real Data Set for Business Forecasting & Data Mining Applications

    Concetta DePaolo, David Robinson, and Aimee Jacobs
    Tuesday, February 21, 2017 - 2:30pm
    We present actual data gathered from a café run by business students. We give examples of time series forecasting and data mining applications, and frame problems as managerial questions to emphasize data-driven decision making.
  • Just-in-Time Teaching in Statistics Classrooms

    Monnie McGee, Lynne Stokes, and Pavel Nadolsky, Southern Methodist University
    Tuesday, January 17, 2017 - 2:00pm
    In this webinar we will present our experiences and provide tips on how to implement a flipped classroom approach we call "Just-in-Time Teaching." In this method in and out of classroom activities are reversed; student preparation before class includes watching a brief lecture via video and responding to web-based discussion questions designed to elicit common misunderstandings students have, and class time is reserved for guided practice to reinforce new knowledge.
  • A data visualization course for undergraduate data science students

    Silas Bergen
    Monday, December 12, 2016 - 2:00pm
    Our university recently began offering a bachelor’s degree in data science. One of the required courses for this major is a course on data summary and visualization. Fall Semester 2016 was the second time this course was offered at our university. In this talk, I will describe the content, structure, and pace of this course and provide examples of student output.
  • A Tour of CAUSEweb

    Dennis Pearl, Director of CAUSE
    Tuesday, November 29, 2016 - 2:00pm
    This webinar will provide a tour of CAUSEweb.org and its special collections and features. The webinar will also provide ways for community involvement in building the collections and seek audience suggestions for future projects.
