Field notes
The sample exercise models a funnel with three rates: people who visit after seeing an ad, visitors who add to a basket, and baskets that convert to purchases. The homepage says the business lessons include sliders for balance sheets, funnels, and queues; it also lists 33 machine-learning lessons and 19 space-and-nature lessons. These counts and privacy statements are presented by the site itself.
