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:

In science experiments, complete data collection is crucial. Rupal's conclusion about the most reactive metal based on only half - of an experiment means there is insufficient data. Geoff's act is data plagiarism, Shelby's is a procedural error, and Juan's is a unit - recording error.

Answer:

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