A scientist wanted to test whether frogs jump different distances if they are kept at different temperatures. He kept one group of frogs at 40 degrees Fahrenheit, another at 55 degrees Fahrenheit, and a third group at 70 degrees. He found that frogs kept at higher temperatures can jump farther than frogs kept at lower temperatures. What is the test variable (independent variable) in this experiment?

Back

temperature

What is the outcome variable (dependent variable) in the experiment where a scientist tested frog jumping distances at different temperatures?

Back

distance
