3-1
1. (3 points) Using the given scenario, determine the
IV, DV, and Control Groups.
Dr. Imanut wants to examine whether a new drug increases
the maze running performance of older rats. Just like aging
humans, older rats show signs of poorer memory for new
things. Dr. Imanut teaches two groups of older rats to find a
piece of tasty rat chow in the maze. One group of rats is
given the new drug while they are learning the maze. The
second group is not given the new drug. One week after
having learned the maze he retests the rats and records how
long it takes them to find the rat chow.
2. (2 points) A report in the media states that a specific diet
will protect individuals from cancer. However, no data are
reported to support this statement. Is this statement a
hypothesis or a conclusion? Explain why.
