Question

which portrays inadequate data?
geoff uses another classmates data because he forgot to record his own experiments 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.
juan records the density of acetone in grams per cubic liters instead of grams per milliliters.

Explanation:

• Geoff: Using another classmate's data is data falsification, not inadequate data.
• Shelby: Switching steps in a procedure is a procedural error, not related to data adequacy.
• Rupal: Completing only half of an experiment means there is not enough data (inadequate data) to accurately determine which metal is the most reactive.
• Juan: Recording density in the wrong units is a unit - conversion error, not inadequate data.

Answer:

Rupal determines aluminum is the most reactive metal by completing only half of her experiment.
