Webinar Series

StatPREP webinars help instructors to familiarize themselves both with lessons and the underlying techniques for teaching data-centric data. Below are the recordings of past webinars.

Past Webinars

The following are descriptions and recordings of past webinars.

Using the Little App “Linear Models”

March 27, 2019 {#Webinar-2019-03-27}

The webinar presents a Little App called Linear Models, formally Regression and Smoothers. This is the first look at the redesign of the Little Apps. This Little App will allow teachers and students to pick between 4 different datasets and then particular variables to investigate a linear regression model between the variables. The webinar will show how to use the Little App in your courses to introduce and investigate regression.The recording of the webinar can be found on YouTube at

Using the “What’s Normal?” Class Lesson to Introduce the Normal Distribution

February 22, 2019 {#Webinar-2019-02-22}

The webinar presents a classroom lesson called “What’s Normal?” that models data which can be used to explain the normal distribution to your class. The lesson shows the connection between data and the empirical rule of the normal curve. The recording of the webinar can be found on YouTube at

Introducing Your Students to Multivariable Data

Friday January 25, 2019 {#Webinar-2019-01-25}

This webinar presents a way to introduce students to data. The webinar will present two classroom lessons that can be used to explain multivariable data to your class. The first is called “A Lesson for the First Day,” and is used to show your students how data can be used to answer questions. The second is called “Using Google Spreadsheets,” and has your students collect data in the classroom. Both of these activities can be completed early in the course.

Using Little Apps to teach Two-sample t

Friday October 26, 2018 {#Webinar-2018-11-26}

The webinar demonstrates how to use the little app on Two-sample t in class and use the little app on proportions. Lastly the webinar shows the tutorials on sampling and resampling if people want to introduce modern methods in statistics. The recording of the webinar can be found on YouTube at

Using StatPREP Little Apps to Teach Descriptive Statistics

Friday, Sept 7, 2018{#Webinar-2018-09-07}

This webinar’ focus is on the nuts and bolts of designing a class lesson around using the little apps for teaching descriptive statistics.  The webinar will include:

  • Where to find the little apps
  • How to use the little app to demonstrate center and spread
  • Picking different response variables
  • Showing mean and standard deviation in the graphical output
  • Showing 95% confidence interval to introduce the idea of inference
  • Choosing an explanatory variable and then discussing difference in means
  • Some comments on sample size
  • Types of assessment that could be done
  • Time for webinar participants to ask questions

Getting a handle on ANOVA

Friday, April 20, 2018 {#Webinar-2018-04-20}

This webinar is about ANOVA, seen from a perspective that we think makes it much easier to understand and is rooted in a display of data. Kate Kozak will lead the webinar. Come find out from her what you have been missing and how to become confident in teaching ANOVA with data.

This will be our first webinar about the Little Apps series, interactive displays of data designed to let you an your students explore a statistical method or idea. This webinar features the app on one-variable ANOVA.

Writing an interactive tutorial

Friday Dec 1, 2017 {#Webinar-2017-12-1}

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’ll start by creating an Rmd file with some simple but authentic statistical content. Then, we’ll add slots for multiple-choice questions and computations. Finally, we’ll activate the components that turn an ordinary Rmd file into an interactive tutorial.

To participate fully in the webinar

  1. Make sure that you have access to an RStudio system with these packages installed: learnr,shinyknitrmarkdown, and mdsint (which you need to install with the R command devtools::install_github("dtkaplan/mdsint").

– If you are a StatPREP participant, you can request an account on the StatPREP RStudio server. The necessary packages are pre-installed.
2. Download to your laptop or desktop the Writing_tutorials_1.Rmd file containing the tutorial. In the course of the webinar, you’ll be editing this file in your account on the StatPREP RStudio server.

Using RStudio to manage your website and write course handouts

Friday Oct 27, 2017 {#Webinar-2017-11-27}

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 is an introduction to RStudio with a focus on creating and updating course web sites and writing course handouts. We’ll start by introducing the RStudio editor, which enables you to revise documents or create new ones. You’ll learn how to link your RStudio account to GitHub so that you can manage your course web site from within RStudio. You’ll also see how to create documents for class handouts: simultaneously generating printable PDF and web versions.


  1. You need an account on the StatPREP RStudio service. You can get an account by submitting this form. We also have some guest accounts available for last-minute arrivals. Needless to say, the service is free.
  2. You need a GitHub account. This is also free. If you already have a GitHub account, use that. If you don’t, set one up now at

Setting up your own course web site

Friday Sept 29, 2017 {#Webinar-2017-09-29}

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’ll focus on another approach which requires no institutional resources and uses a completely free web service: GitHub. In the webinar, we’ll go 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’ll demonstrate 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.
