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.
Points of webinar etiquette
- 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.
- 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.
- 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).
- 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.
- 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 GitHub.com 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.
- 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.
- 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.
- 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.
Here’s a video showing how to join a StatPREP webinar using the “Zoom” software:
In the video, both our earnestness and evident lack of experience are apparent. We’ll need to remake it eventually, but here’s the outline:
- At the start, Kate has set up the webinar and is as yet the only participant. Her picture appears on the screen.
- Danny telephones Kate and pretends to be clueless. (It’s type-casting!) You’ll hear clean audio from Kate, and poor-quality audio because Danny is using a telephone rather than the Zoom software.
- Kate tells Danny where to find the link to the webinar itself. (It’s on this very page!) Danny clicks the link and then almost inaudibly narrates the events as the Zoom system sets itself up in Danny’s web browser.
- Suddenly Danny’s audio improves markedly and a video feed from his computer appears on Kate’s screen. Danny and Kate discuss how to mute and unmute audio and how a participant can share his or her screen with the rest of the participants. Unfortunately, our amateur video continues to show the StatPREP.org web page instead of showing the Zoom control screen which has the mute and share-screen buttons. But you will see the Zoom control screen.
