Alab researcher wants to find out whether mice will run through a maze quicker during the day or at night, after training. he has 100 mice available. he randomly assigns 50 of them into ech group. he trains the first group to run the maze ar 9: 00am and trains the sevond group to run the maze ar 9: 00 pm. each mouse is trained the same way, and the last 3 years run times are recored. describe what is being measured in this experiment and what variable is being manipulated?

In this case, since the run times are the one being compared and recorded, therefore the data being measured in the experiment is the run times.

The difference of the two groups of mice is the time of the day that the mice run, day or night. Therefore the variable being manipulated is the time of the day.
