Mike's Experiment: Comparison Between Hike And Nike Commercials

Mike’s Experiment Mike’s hypothesis is people will drink more soda while watching a Coke commercial in comparison to a Nike commercial. The dependent variable for this experiment was the amount of soda drunk by the test group. The dependent variable was supposed to depend on the commercial shown, the Coke commercial or either the Nike commercial. This is the independent variable because this variable does not depend on another variable. The experimental group was subjects who drank Coke, while watching either the Coke or Nike commercial. No control group was shown in this experiment. A strength in Mike’s test is the contrast between the commercials. If more people drink more Coke during the Nike commercial that could mean that people do not need to watch people drink Coke to drink more, but a distraction like the Nike commercial to hold their attention to allow them to drink more. Another good thing Mike did was that he assigned his groups randomly. This will make the experiment more accurate if he was not biased. He could have been biased because as a friend to the test group he might know their likes and dislikes. Mike’s experiment was practical. This allows him to easily come up with a
However, his conclusions cannot be generalizable. This is because his test groups were too small. He can not compare ten people to the amount of in the whole world or even one city. Also he only chose his friends for his experiment. He did not tell us the diversity among his friends, so we can therefore infer that his friends might come from similar backgrounds and are around the same age group. Also, we can not assume that everyone prefers coke therefore we cannot use coke to represent all sodas that people like to drink. With the changes of the weaknesses shown Mike’s experiment would be more
