Teaching Tools

I’ve put together a few interactive tools to help me throughout the course.

Interactive Timer

Open Timer Tool

This game-show style buzzer lets you set a countdown and alerts you when time’s up. We used it extensively to keep our movie assignment on track! Press ‘S’ to access the settings panel, space to start/pause, and ‘B’ to sound the buzzer.

Datasaurus Dozen

Open Datasaurus Tool

Run ggplot in the browser to demonstrate why visualization is important! All these datasets have nearly identical summary statistics (mean, standard deviation, correlation), but they look wildly different when plotted.

Measures of Central Tendency

Open Central Tendency Calculator

This simple tool lets you experiment with mean, median, and mode calculations. Try entering a set of values with some extreme outliers, then observe how each measure responds differently. I used it to demonstrate how resilient the median is to extreme values.
