Question
A pharmaceutical company has developed a new drug. In preliminary tests, the drug reduced high blood pressure in laboratory animals when injected under the skin. A second experiment was designed to more thoroughly test the drug's effectiveness. One thousand male rabbits were tested. Five hundred received the drug through injection (Group "A") and five hundred did not receive the drug or an injection (Group "B"). All rabbits were of the same breed, were fed the same type and amount of food, and were housed under identical conditions. After the drug was administered, Group "A" had decreased blood pressure for approximately one hour, then it returned to normal. The blood pressure of Group "B" remained unchanged and normal.
a- Is this discovery science or hypothesis testing science?
b- Which is the experimental group?
c- Which is the control group
Explanation / Answer
a- This is a hypothesis testing science, where the pharmaceutical company is testing the effectiveness of a drug between two groups.
b- "Group A" is the experimental group because this group received the drug through injection.
c- "Group B" is the control group as this group did not receive any drug or an injection.
