Jahyr Duenas (9) conducted an experiment titled, Exposure to Striking Imagery and Test Scores in Mr. Bowen’s science class.  His findings are as follows:

Discussion: Everyone always wants to know ways on how they can get better test scores and succeed better in school, especially now at the end of the school year.  For that reason, we conducted an experiment on students to see if their test scores would increase with the increase of adrenaline.  Striking imagery induces fear and surprise in some people and makes adrenaline release systemically.  The adrenaline is known to increase brain activity.

Question: Can being exposed to striking videos increase test scores for high school students?

Hypothesis: Being exposed to striking imagery before an assessment will cause test scores to increase.

Procedure: The students were asked to stand in the back of the class and face the wall. Then students, chosen at random, turned around and looked at a one minute video that portrays professional skateboarders falling and becoming injured. Then they were asked to turn back around and the rest of the class turned around. A blank screen was shown to them for a minute as well. Next, the students were given  a test and the scores were put into a data chart.

Data:  The data presented here is the raw score correct out of 30.

We performed a one-tailed homoscedastic T-Test on the data which returned 21%.  This means it’s 21% likely that the two datasets are not independent from each other or rather it’s about a 79% that the striking imagery caused an increase in test score.

Conclusion: We can confidently conclude there is some merit to our finding here, and there may be reason for teachers and students to engage in some sort of adrenaline engaging activity before important assessments.  However, we need to conduct further investigation by varying the type of striking imagery used, and diversify our test population beyond a single classroom.
