Answers determine the team ranking.

Example leaderboard

Fictional scores to illustrate the display. These are not student results.

Cedar wins. Each participating member receives +1 percentage point of the overall course grade after ID and attendance checks. If two teams tied for first, both would win.

What earns points?

• Round 1 · 6 points. Complete contract cost, sample selection and decision errors.
• Round 2 · 12 points. Statistical models, test statistics, conclusions and p-values.
• Round 3 · 12 points. Cash, changed contract terms, confirmation evidence and sunk costs.

Every correct answer earns 2 points. Incorrect or missing answers earn 0. Numerical tolerances appear beside the input. Each question supplies the figures it needs, so one arithmetic mistake does not change the benchmark for the next question.

How it works in class

1. The instructor opens a round. The captain saves the team’s answers using its private code.
2. The team can revise until the instructor closes the round. The latest saved version counts.
3. Closing the round releases automatic points and cumulative team ranks.
4. After the final round, the instructor finalizes the winners and exports the bonus list. Students can then inspect their own marked answers and solutions.

No points for speed, agreeing with the class vote or a fortunate scenario. Business recommendations remain open to discussion. No instructor marking is needed for the ranking.
