Question

Which portrays inadequate data?

Geoff uses another classmate’s data because he forgot to record his own experiment’s temperature readings.
Shelby accidentally switches steps 3 and 4 while writing her laboratory procedure.
Rupal determines aluminum is the most reactive metal by completing only half of her experiment.

Answer 1

Geoff and Rupal.

- Geoff: he’s missing his own temperature readings and is using someone else’s data, so his dataset is incomplete (and improperly sourced).
- Rupal: she stopped halfway, so she doesn’t have the full set of results needed to support her conclusion.

Shelby’s mistake is a procedural/organizational error in writing the procedure, not inherently a problem of having inadequate data.
