Anna is conducting an experiment to determine how weather affects cell phone reception. She is trying to decide the best way to conduct her experiment in order to collect meaningful data.

Question

Which of the following experiments would help Anna collect the best data?
A.
Test a cell phone's reception in the exact same location under various atmospheric conditions.
B.
Test a cell phone's reception in one location with clear weather and in another location with rainy weather.
C.
Test different cell phones in different locations on days with clear weather.
D.
Test different cell phones in different locations on days with rainy weather.

Answer 1

A. Test a cell phone's reception in the exact same location under various atmospheric conditions.

By keeping the location constant and just changing the atmospheric conditions, Anna will be able to more accurately determine the effect of weather on cell phone reception without the interference of other variables like location. This will help her collect the best data for her experiment.
