- Learning target and evidence
- Introductory statistics. Target: choose mean or median for a supplied dataset and justify with distribution/extreme-value evidence. Success: correct calculation and conditional justification. Prior work shows many learners say median is always better when an outlier exists.
- Learners and access
- 24 adult learners. Some have phone access but home internet cannot be assumed. Printed alternative required. Calculators available in class. No personal financial disclosure.
- Course constraints
- 60-minute class. Pre-class maximum 10 minutes, ungraded diagnostic. Follow-up maximum 15 minutes due in three days, low stakes. Teacher can give whole-class and checklist feedback, not individual written comments to all.
