Jack the scientist had a hypothesis. He thought that frogs would be able to jump farther if they had stretched their legs first. He thought that if they were limber and warmed up, that just like a human athlete they would be better able to perform.
So Jack got two groups of frogs, his “experimental” group and his control group. There were five frogs in each group. He put the experimental group in a frog playground, and let them jump around for two minutes – long enough to get warmed up, but not long enough for them to get tired. He kept the control frogs in their boring cages, and they didn’t jump around at all. Then, he took the frogs one by one and put them on a floor he’d marked out with a meter stick, and poked each one gently to make them jump. He wrote how far each had jumped in his notebook.
Jack found that the frogs that had been warmed up in the playground jumped on average 50 centimeters, with a standard deviation of 5 cm, while the control frogs jumped an average of 30 centimeters, with a standard deviation of 2 cm. Jack wrote up his experiment and submitted it to The Journal of Frog Biomechanics, and after being reviewed by a bunch of other Frog scientists, it was published.
