StatPREP Webinars



April 2022 Webinar Past, Present, Future of StatPREP

Thursday, April 21 4 pm to 5 pm (EDT), 3 pm to 4 pm (CDT), 2 pm to 1 pm (MDT), 1 pm to 2 pm PDT (MST)

Hosts: Kathryn Kozak and Ambika Silva

StatPREP started with the goal of convincing instructors that intro statistics courses should be data-centric! Over the course of the grant we gave participants access to free tools from StatPREP to help students learn introductory statistics concepts, including Little Apps along with tutorials that introduce RStudio. In this webinar, we will reflect on both what StatPREP has accomplished and what is on the horizon as we look towards the future.

March 2022 Webinar Three Ways to (Re)invigorate Your Teaching of Linear Regression

March 2, 2022, 5:30 pm to 6:30 pm EST, 4:30 pm to 5:30 pm CST, 3:30 pm to 4:30 pm CST, 2:30 pm to 3:30 pm PST

Learn three ways to invigorate or reinvigorate your teaching of linear regression in our upcoming webinar facilitated by Dr. Helen Burn from Highline College. The webinar is relevant whether you are still formulating your approach to teaching linear regression or if you wish to give new strength or energy to your current approach. The session will be interactive and activity-based, leveraging the StatPREP Little Apps to demonstrate and apply ideas. However, the ideas shared and discussed in the webinar can be immediately applied to your statistics class whether or not your students have access to technology. Three ways to (re)invigorate your teaching of linear regression shared in the webinar are:

  1. Focus on the response variable and the guiding question: What predicts the explanatory variable?
  2. Increase students’ capacity to assess the suitability of a linear model through exploring and examining sample variability, model strength, and slope as effect size.
  3. Learn from the StatPREP team about what it means to be forward-thinking around the topic of linear regression and the different settings in which regression is used in practice.

September 2021 Webinar Experiencing Sampling Variation Early and Often in an Intro Statistics Course

Using data centric lessons and visualization tools such as the “Points and Densities Little App” have supported my students’ understanding of the key role sampling variation plays in statistical investigation. I love overhearing “Hey, my sample looks different from yours!” It opens the door to explore whether there is still a consistent story to tell about a variable.

There are many materials on the StatPREP site that can help you teach data-centric statistics. This webinar described some of these resources that are ready for Fall 2020.

August 7, 2020 Building Community in a Remote Learning Environment

A sense of belonging and community is still critical to ensure that students remain engaged and enthusiastic while being in a remote learning environment. Students may be accustomed to find a sense of belonging from interactions with their peers and classmates in a physical classroom setting. As instruction is delivered virtually, students may likely feel less connected, uncertain, or distracted in their new learning environment. Creating a virtual community is just as important for remote learning as it is in a physical classroom. This webinar presented suggestions to help educators reestablish a sense of belonging for their students.

May 18, 2020 What Every Instructor Should Know About the Bootstrap

Statistical concepts such as sampling distributions, standard errors, and P-values are difficult for many students. A good way to get hands-on experience with these abstract concepts is using bootstrapping and permutation tests, and we’ll demonstrate using a variety of examples. Though bootstrapping has enormous potential in statistics education and practice, there are subtle issues and ways to go wrong. For example, the common combination of nonparametric bootstrapping and bootstrap percentile confidence intervals is less accurate than using t-intervals for small samples, though more accurate for larger samples. The goals of this talk are to provide a deeper understanding of bootstrap methods – how they work, when they work or not, which methods work better– and to highlight pedagogical issues.

April 23, 2020 Little App Update

We celebrated the third anniversary of the StatPREP Little Apps by launching a brand new set of apps with a new look and new functionality. Among the changes are a dramatically increased choice of data sets (including those keyed to textbooks often used by StatPREP instructors) and the ability to upload your own CSV files, a feature that lets you freeze a display and show it side-by-side with the current display. The original apps continue to be available at their original web addresses, but we encourage you to switch to the new ones and try out their new capabilities.

March 26, 2020 The p-value: Replacing 0.05 with Understanding

The American Statistical Association’s 2016 P-Value Statement and The American Statistician’s 2019 special issue “Statistical Inference in the 21st Century: A World Beyond p < 0.05” both provide a call for action and change regarding how p-values are taught and used. In particular, they discourage the focus on whether a p-value is less than a specific threshold (e.g. 0.05), and encourage a better understanding of what the p-value actually represents. This talk will discuss ways to replace “p < 0.05” with conceptual understanding of a p-value in introductory statistics courses.

December 12, 2019 The Compact Guide to Classical Inference: Why?

In Dec. 2019, started the serial publication of a short book for instructors: The Compact Guide to Classical Inference. (Note from March 2020: The full book is available here.]( Keeping in mind that StatPREP is about centering statistics education on real data, this book is an anomaly: the introduction of a reframed mathematical approach to statistical inference. The reframed approach unifies into a simple, single standard procedure all the inferential settings found in introductory statistics and carries forward to apply to “advanced” settings such as multiple regression.

Presenters: Donna LaLonde & Danny Kaplan

The webinar was a conversation between Donna and Danny about how the many formulae and probability tables of historical statistics can be unified into a single simple test statistic, F, and an expression for the confidence interval in terms of F.

Dec 1, 2017 Writing an interactive tutorial

An interactive tutorial is an effective way to provide access to data computing to students. Tutorials can be arranged so that a student needs nothing more than a web browser. Within a tutorial, you can pose multiple choice questions, display results of statistical calculations, and provide students with an R session in which they can do their own calculations (with as much or as little guidance from you as you want).

The first step in writing an interactive tutorial is to figure out what you want the tutorial to cover. In the webinar, we started by creating an Rmd file with some simple but authentic statistical content. Then, we added slots for multiple-choice questions and computations. Finally, we activated the components that turn an ordinary Rmd file into an interactive tutorial.

October 27, 2017 Using RStudio to manage your website and write course handouts

You can start teaching with StatPREP without having to set up any statistical software; all our tutorials are available through an ordinary web browser. But many instructors are interested in going deeper. In particular, we’ve had many calls for instruction on how to use RStudio to create your own documents or customize those available through StatPREP.

RStudio provides the means to write course notes, handouts, and even interactive tutorials. Together with GitHub, it lets you easily set up course-specific web sites and create materials for those sites. Oh … and since it built on the R software, it’s fully integrated with modern systems for data management, statistics, modeling, and even machine learning.

This webinar introduced RStudio with a focus on creating and updating course web sites and writing course handouts. We started with the RStudio editor, which enables you to revise documents or create new ones. Also covered: How to link your RStudio account to GitHub so that you can manage your course web site from within RStudio; and how to create documents for class handouts—simultaneously generating printable PDF and web versions.

September 29, 2017 Setting up your own course web site

A course web site is an essential resource for an instructor: it provides a place for you to post links to StatPREP lessons as well other tutorial material and data sets of particular interest to you and even your own course handouts. Many instructors have access to “course management software” systems such as Blackboard or Moodle to which students can log in and view a home page. We focused on another approach which requires no institutional resources and uses a completely free web service: GitHub. In the webinar, we went through the steps of setting up a GitHub account and a course “repository”“which serves a complete website with an address like (where you’ll customize the ID and course name to suit your situation). Then we demonstrated how to create a web page that can include links to StatPREP tutorials and other resources you choose, upload data sets so your students can easily access them, and all the other things that can make your course more accessible and engaging for students.
