Question

a group of scientists conducted a research study to test the hypothesis, if schools are kept at colder temperatures, more students will get sick. the scientists do their study at a school that maintains a constant temperature of 15c (60 f). the scientists found that 45% of the students at the school caught colds from december to march. the results support the hypothesis and the scientists conclude that colder temperatures in schools result in more students getting sick. when the research was sent to publish their findings, a respected journalist rejected it. what was the most likely reason for the results not being published?
a. the study is flawed, since the experiment was only at one school and there is no control group
b. the research study was conducted for an insufficient amount of time.
c. the study is flawed because there is an insufficient number of students included in the research study.
d. another group of scientists did not discuss it with the original researchers.

Explanation:

A proper experiment needs a control group. Testing at one school without one makes the study flawed.

Answer:

The study is flawed, since the experiment was only at one school and there is no control group.
