CW#10 Part A: Multiple Sets of Data

A science class was studying 2 different frogs; bullfrogs and leopard frogs. Each species had a distinct-sounding croak, so it was easy to tell the sounds apart. They noticed that both frog species seemed to croak at different rates when the temperature changed. Being curious scientists, they designed an experiment to see if temperature really affected the frogs’ croaking rates.
