I apologize for the confusion in my previous response. If a controlled experiment is deemed too risky or unethical, a field study may be the best alternative. In a field study, researchers observe and collect data in a real-world setting, without manipulating variables or controlling conditions as they would in a controlled experiment. This type of study allows for more natural and authentic observations, while still providing valuable insights and data.

A student records the time it takes for her pet rabbit to make it through a maze to a carrot. In one test, she has the rabbit try to find the carrot at 8:00 AM after eating its first meal of the day. In the other test, the rabbit tries to find the carrot at 8:00 AM without having eaten its first meal of the day.
In this experiment, which variable is the outcome variable?
the time of day when the rabbit starts the maze
the time required to finish the maze
whether the rabbit is hungry or not
whether or not the rabbit finds the carrot
The time required to finish the maze is the outcome variable in this experiment.
