Read What a Measure Actually Counts
Distinguish completed attempts, people, and quality.
Supplied materials
- Original fictional report: “During an open model session, the table recorded 20 completed attempts. Eleven attendees made the attempts; some made more than one. An attempt counted as complete when all steps were tried, whether or not the model held together. No later quality check was done.” Draft claim: “Twenty people made lasting high-quality models.”
- Paper and pencil; spoken responses are welcome.
Learn the idea
A measure’s definition determines what a count means. Here the counted unit is completed attempts, not people. Completion means trying all steps, not meeting a quality standard. The report also distinguishes twenty attempts from eleven attendees and explicitly lacks a later check. Those definitions are central evidence, not optional technical details.
An accurate summary keeps unit, criterion, and time scope aligned. “Twenty attempts met the tried-all-steps criterion during the session” is supported. Lasting high-quality models adds a quality judgment and later outcome absent from the record. Definitions may limit a claim while still leaving the original count useful for understanding activity at the table.
- Underline the counted unit and count.
- Identify the number of attendees separately.
- Restate the completion criterion in plain language.
- Revise the draft and identify the missing quality and later-time measures.
See the method in action
Eleven attendees made twenty attempts that counted as complete because all steps were tried. The report does not say every model held together or lasted. It measures session activity under a defined criterion, not durable quality.

See the answer and explanation
Eleven attendees made twenty tried-all-steps attempts; model quality and durability were not checked.
The revision preserves people, attempts, and the completion definition, while retaining absent quality and later checks. The other options change the unit or invent outcomes.
Take it further
Change the definition to “Complete means the model held together during a one-minute check.” Model: the twenty attempts now meet a short-term structural criterion, not merely step trying. A one-minute check still does not establish lasting durability or performance by twenty distinct people.
