Constructed teaching data: these values were invented for this activity, not collected in an experiment.
Matched samples start at 10.0°C in a 22°C room. Separate 20-minute trial endpoints are shown to 0.1°C. Instrument accuracy is not supplied.
| Trial | Sleeve E (°C) | Sleeve F (°C) |
|---|---|---|
| 1 | 14.0 | 14.2 |
| 2 | 14.4 | 14.0 |
| 3 | 14.2 | 14.3 |
Extension question 1
Do these records justify a confident preference for E or F? What would you check next?
Optional further reasoning
Explain why displaying tenths of a degree does not by itself establish instrument accuracy. Name information you would need before interpreting a small difference.
