Analyzing Pilot Results for Focus and Productivity

Current Situation and Strategic Decision

The team conducted a one-week pilot with 25 students. The results are mixed: 20 students tried the tool, but only nine used it consistently, eight indicated they would pay, and many lost motivation over time. While the team is encouraged, they remain uncertain. The key decision is not to scale yet. Instead, they will run a targeted iteration to diagnose the engagement drop-off, specifically by interviewing the 11 students who tried the tool but stopped using it.

Final Exam Item Pool - Part 1

Section 1: Levels of Measurement

1. A developmental psychologist records children’s ages in full years. A colleague argues this variable should be treated as ordinal because one cannot be certain children aged 6 and 7 differ by “exactly one year” in psychological maturity. Which response best evaluates this argument?

• a) The colleague is correct; developmental maturity is inherently ordinal.
• b) The colleague is incorrect; age in years has equal intervals and a true zero, making it ratio.
• c) The colleague is correct because ratio measurement requires a psychological, not just physical, zero point.
• d) The colleague is incorrect because classifying a variable depends on conceptual intent, not physical properties.
