Question

Charles Hillman, an associate professor at the University of Illinois, is conducting research into why children are better at problem-solving after exercise. He places 20 kids, approximately 10 years of age, on a treadmill for 20 minutes. Another group of 10-year-old kids sits in a chair for 20 minutes. Dr. Hillman then measures the brain wave activity of both groups. The group who exercised showed a 5% increase in the P3 waves, which occur during decision- making. What would need to be done in order to make this experimental outcome accepted in the scientific community? Group of answer choices More time would need to be allowed for the experiment. Other scientists would need to confirm the results by performing the same experiment. The same test would have to be done using a different type of exercise. Girls and boys would need to be tested separately and then together.

Answer 1

Other scientists would need to confirm the results by performing the same experiment.

Step-by-step explanation:

According to this question, an experiment was conducted by an associate professor, using 20kids, to discover why children are better at problem-solving after exercise. He arrived at a result that Children who exercised showed a 5% increase in the P3 waves, which occur during decision- making.

However, in order for this findings by Charles Hillman to be generally accepted and recognized in the scientific community, which is a connection of several scientists, the results need to be confirmed by performing the same tests or experiment.

Note that, an experiment becomes a scientific theory if it has undergone series of repeatable tests. One of the key features of scientific experiment is that it must be repeatable.
