Match the question to an observable outcome
Twenty-four objects arrived. Ten worked at departure. Those are different events, and neither directly measures avoided waste. An object awaiting a part may later work; an object working at departure may fail again. Even continued use would not alone tell you what would have happened without the café.
Write the question with a unit, place, time and outcome. “What happened to objects at this event’s closing?” fits the log. “How much waste do repair cafés prevent?” needs a broader design, follow-up and a defensible comparison. Neither question is inherently better; they demand different evidence.
A source plan connects each subquestion to a possible record. For departure status, inspect the outcome log and its categories. For durability, you would need later observations or reports with dates and a response record. For skill learning, you would need a suitable measure of learning, not just attendance or enthusiasm.
Avoid designing an investigation you cannot carry out responsibly. This course does not require contacting participants or collecting personal information. The supplied packet supports analysis and a clearly labeled practice feature. If you choose real research, begin with accessible public sources and keep the question within what you can inspect.
Your scope note should state both a useful contribution and a limit. “We know nothing” discards the log’s real descriptive value. “The event solved waste” exceeds it. A precise account of immediate outcomes, paired with questions for follow-up, gives readers something informative without inventing impact.
