Check what you learned in chapter 1. Six rounds: the key words, met in new moments, then all four lessons at once on a city bus app. One score at the end.
You have learned four things in this chapter. This lesson checks them, in six rounds.
The first five are the key words. You meet each one in a new moment, not the one you learned it in. The last round uses all four lessons at once, on a product you haven’t seen. You get one score at the end, and you can try again.

Round 5 of 6
How strong is the proof?
Leo wants to know if the bus app's Buy button is hard to find. Put this proof in order, from weakest to strongest.
Weakest proof
- The app's log shows 4 in 10 riders open the menu before they find Buy.
A trace, counted across every rider.
- Leo thinks the Buy button is hard to find.
Nobody has checked it yet.
- Leo moved the button, and now fewer riders open the menu first.
He changed one thing, and the count changed with it.
- One rider tells Leo she couldn't find the Buy button.
A good place to start, but one person is not proof.
- Leo watched 5 riders. 3 of them looked around before they tapped Buy.
What people did, not what they said.
Strongest proof
Drag a card up or down, or use its arrows. Then check your order.
See the right order
- Opinion: Leo thinks the Buy button is hard to find.
- One story: One rider tells Leo she couldn't find the Buy button.
- What you saw: Leo watched 5 riders. 3 of them looked around before they tapped Buy.
- What you counted: The app's log shows 4 in 10 riders open the menu before they find Buy.
- A fair test: Leo moved the button, and now fewer riders open the menu first.
Round 6 of 6
Use it all on a new case
6 questions on a product you haven't seen in this chapter. Say how sure you are each time.
Leo runs a city bus app. People buy a ticket in the app, then show it to the driver. Leo's team found three things.
- Many people buy a ticket, then buy a second one less than two minutes later.
- Some people take a screenshot of their ticket before they get on the bus.
- In a survey, 9 out of 10 people said the app is easy to use.
Question 1 of 6
It is about who they want to be, not today's task. That is an aspiration.

Question 6 of 6
The reason lives with the riders. AI can't stand at the stop and ask why. A pop-up treats the sign as if it were the problem.
