A debate exists in the company whether it is better to provide potential customers with the opportunity to play a demo of the game or to rely upon a video advertisement of the game. The CEO of the company decides to test his hypothesis that actually playing the video game demo is the best way to increase the likelihood of a potential customer purchasing the game. Participants MGC put an ad online in an effort to obtain subjects for their study. The first 100 people that responded with interest were selected to participate. Of the 100 participants, all were under the age of 30. 75 of the participants were male and 25 of the participants were female. Method Marketing researchers for MGC assign half of the participants to play the video game demo themselves for 10 minutes, while the other half of participants watch a 90 second ad of the game’s key moments. Participants rate how likely they are to buy the game on a scale of 1 (not likely) through 10 (very likely). Results are presented in the table below. At the conclusion of this study, participants were informed that they were being tested to see which marketing technique might make them more likely to be interested in purchasing the game. Results and Discussion Participants’ Observed the Game Ad Personally Played Game Rating (n = 50) (n = 50) Mean 6.31 2.04 Standard 1.25 0.80 Deviation  Unit 2 Practice Test – Biological Bases of Behavior A.

B – Rating on a scale of 1-10 of how likely they are to buy the game. C – Participants that personally played the game had a smaller standard deviation, meaning that their ratings were more similar to one another. D – Debriefing was used to inform the participants of the true nature of the experiment. E – The results are not very generalizable because they only used participants under 30. The participants were also disproportionally men. F – Refutes the hypothesis because the mean score of those who watched the ad was higher than those who actually played the game.
