control experimental dependent variable independent variable
I gave my students this multiple choice question: A drug company developed a pill to reduce cases of stomach virus. To test the medication, half of the participants got the pill with the new medicine and half got a sugar pill. Which term best identifies the participants who got a sugar pill?

Only one answer is correct among these 4 choices:
- control
- experimental
- dependent variable
- independent variable

Could you tell me which one is correct?

control
