Laura has two pet iguanas in separate glass tanks. She wanted to test the best Lighting for her pet iguanas' cages, so she put a
bright lamp above one cage and a dim lamp above the second cage. For two weeks, she took notes about their sleeping patterns,
how often and how much they ate, how they responded to her, and any other behaviors she noticed. She plans to organize her data
in a graphic way.
Which of these graphic representations would most clearly help Laura show similarities and differences in behaviors of her
iguanas?
