Software for teaching creative writing. An educational software company wants to compare the effectiveness of its computer animation for teaching creative writing with that of a textbook presentation. The company tests the creative writing of each of a group of second-year college students and then randomly divides them into two groups.
One group uses the animation, and the other studies the text. The company retests all the students and compares the increase in creative writing in the two groups. Is this an experiment? Why or why not?
