Behind the Scenes: transforming traditional to data-centric. Part I

It seems so sensible to say that statistics should be data-centric. But traditionally statistics has been taught as an extension of mathematics. Data didn’t enter into it except as fodder for exercises and test questions.

In this Behind the Scenes series, we’ll look at some examples of turning traditional lessons into data-centric ones. Read more

Lesson: An Experiment with Paper Planes

One of the best ways for students to learn about data is to collect and enter data into a shared spreadsheet. This lesson (link to tutorial document) does exactly that.

On the surface, the lesson is about performing an experiment, Read more

Lesson: Driver reaction times

An all-too-common style of statistics exercise gives students some numbers and asks them to calculate a confidence interval or conduct a hypothesis test.

The StatPREP driver-reaction-time lesson is our re-interpretation using data and computing of a textbook-type exercise that asks for the confidence interval Read more

Lesson: Data and Diabetes

All of us hear about risk factors for disease and all of us undergo medical screening tests. This lesson uses data from the National Health and Nutrition Evaluation Survey (NHANES) to illustrate how a screening test can be constructed. Link to lesson document.

Participating in a Webinar

Points of webinar etiquette

  1. We’ll activate the webinar link 15 minutes or so before the webinar. This will let you establish and check your connection to the webinar before it starts. Once it’s working, let the connection continue.
  2. We definitely want you to participate actively, but when there are several people participating, we will be hearing the background noise from several different sources. So mute your audio input (there’s a button) until you want to say something. At that point, have at it. Use your own judgment about when to re-mute the audio. This is not the world of 1960s television with the “Roger”, “Over”, and “Over and out.” If you are in a dialog, then leave your audio unmuted.
  3. Shortly before the official start time, we will turn on the recorder. This is a good time to double-check that you have muted your audio input so that your sighs, exasperations, and witty critical observations don’t show up on the recorded video (unless you want them to).
  4. The initial part of the webinar will be a presentation, so the webinar organizers will be controlling what appears on the screen. Do feel free to ask questions that will be of general interest.
  5. The presentation will typically involve to some extent the carrying out of a task. For instance, in the very first webinar, the task involves creating a account, setting up a repository, and editing a file on GitHub. It might be that you can follow this and carry out the task yourself. But that’s not obligatory. Feel free just to watch and listen.
  6. After the presentation part of the webinar, we’ll switch to a “clinic” format. This is where you get to resolve any technical difficulties and there can be a back-and-forth among individual participants and the presenters.
  7. Occasionally you will want to share your screen with the group so that you can show someone else how to do something or can ask someone else for help finding some button or other resource. When you have given or gotten the help needed, unshare your screen so that someone else can have a turn.
  8. The clinic will last up to 90 minutes. Feel free to take a break and come back later. Don’t worry about repeating questions that somebody might have asked earlier. The point is to get things working for you, whatever it takes.
