Drew observed in an experiment that algae in a nearby lake could be found at six meters below the water's surface on a clear day
. On a cloudy day, Drew noted that the algae sat only one meter below the surface of the water. What was the dependent variable in Drew's experiment? the lake that Drew observed the depth at which Drew found the algae the amount of algae measured the sky conditions on a particular day
The dependent variable was the depth at which he found the algae, because that is what he measured on each day.
The independent variable was the sky conditions, since that changed from clear to cloudy, which impacted the dependent variable/the depth of the algae.
