Measure a framed choice without claiming a causal trial
See this course’s project requirements
An original financial decision-case comparison and rule test covering anchored prices, sunk costs, recurring charges and delayed spending with a prewritten decision rule.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A controlled price-anchor comparison and choice explanation.
- A sunk/avoidable cost decision table.
- A twelve-month price comparison and crossover calculation.
- A dated value-comparison record and access-constraint note.
- A framed-choice comparison with explicit design limitations.
- A complete financial decision-case comparison and rule-retest log.
Review and revise
Use these criteria to check your work and choose what to improve.
- All supplied records reconcile and the decision uses the named case rules.
- Calculations show units, intermediate values and a second check.
- Changed-input practice revises the affected result and identifies uncertainty.
- The final project combines six lesson records, separates fictional assumptions from current rules, and states a supported next step.

The idea in everyday life
This is an original fictional practice case. No account, payment, personal record or outside participation is required. Supplied fictional responses: 10 people see price $80 with a $20 reduction, 7 choose buy; different 10 see identical final price $60, 4 choose buy. Groups were not randomized and no other facts are supplied.
Two descriptions of the same dollars can feel different; a small fictional record illustrates framing and does not establish population behavior.
Measure a framed choice without claiming a causal trial — worked practice
Two descriptions of the same dollars can feel different; a small fictional record illustrates framing and does not establish population behavior.
Use paper or a local table; label all amounts as fictional USD unless the case names another unit. Supplied fictional responses: 10 people see price $80 with a $20 reduction, 7 choose buy; different 10 see identical final price $60, 4 choose buy. Groups were not randomized and no other facts are supplied.

Copy as plain text
1. Step 1: Show that the final prices are identical
Show that the final prices are identical.
You should see: 80−20=$60 in both descriptions.
Two descriptions of the same dollars can feel different; a small fictional record illustrates framing and does not establish population behavior.
2. Step 2: Calculate choice proportions
Calculate choice proportions.
You should see: 7/10=70%; 4/10=40%.
Keep this intermediate result so the final decision can be checked.
3. Step 3: Compute the descriptive difference
Compute the descriptive difference.
You should see: 30 percentage points, not 30% of one group.
Keep this intermediate result so the final decision can be checked.
4. Step 4: State what is not established
State what is not established.
You should see: No random assignment or comparable baseline is known, so the record does not prove framing caused the difference.
Keep this intermediate result so the final decision can be checked.
What to finish
A framed-choice comparison with explicit design limitations.
Watch for this
Calling a nonrandomized fictional group difference proof of an effect.
How can I tell I understand it?
Calculate a financial-choice contrast and distinguish descriptive evidence from causation on the supplied changed case while preserving the stated rule and checking the final record.
