As a class we wanted to see who the fastest student was. We lined up all 25 of you on the same course and hit the timer. Each one ran and we clocked your time to get to the end of the course.
What is the independent, control and dependent variable in this experiment?
What is independent= 25 students
control= same course
dependent= time each student ran the course in.
