Question
Information Consider the following scenario: A group of 300 students, between the ages of 18 and 30, were gathered to test the effects of video game use on reaction time. All students reported little to no prior experience using video games. Half of the participants were randomly assigned 50 hours of game play for a fast paced game like Call of Duty, while the other half were assigned 50 hours of game play for a slow paced, strategy game like The Sims. Once the 50 hours of game play were completed, each of the 300 students was tested for reaction times using the same basic procedure. Answer the following eight questions based on the above scenario. This example is taken from a real study conducted at the University of Rochester http://www.futurity.org/video-games-speed-up- reaction-time/ Question 3 (1 point) Which of the following best states the objective of this study? O a) To determine which of the video games uses the eye more effectively. O b) To determine if playing video games affects eyesight. O c) To determine the change in reaction times of students before playing a fast paced game vs a slow paced game. O d) To determine the change in reaction times of students after playing a fast paced game vs a slow paced game. SaveExplanation / Answer
Question 3
Which of the following best states the objective of this study?
Answer:
Correct alternative is d).
d) To determine the change in reaction times of students after playing a fast paced game vs a slow paced game.
Explanation:
For the given scenario, there are total 300 students. Half of the students allocated for playing a fast paced game and half of the students allocated for playing a slow paced game. After playing a game about 50 hours, the reaction times of students were measured. Reaction times measure after experiment and not before experiment.
