Question
Rainbow Labs is developing a pill that treats Fermatisis, a condition affecting Gerlots. Gerlots are found in three main environments: desert, rainforest, and ocean. Several participants from each group were chosen to form a control group. Remaining participants from each of the three environments were grouped together to receive a different dosage of the treatment pill.
Researchers were surprised to find that the Gerlots that received a medium dosage of the experimental pill showed the most alleviation of symptoms.
Why is an experiment the correct method of data collection for this scenario?
a. Rainbow Labs is collecting the opinions of the Gerlots
b. Rainbow labs is trying to determine a cause-and-effect relationship
c. Rainbow labs is observing the Gerlots to see how they behave
d. Rainbow Labs has a really large sample size of data to work with
What is the control group in this context?
A. Gerlots that live in the desert
B. Gerlots that do not have Fermatisis
C. Gerlots that received no dose of the pill
D. Gerlots that received a 50 mg dose of the pill
Why is it important to choose Gerlots from each of the environments for the control group and experiment groups?
A. There are more Gerlots in the desert than in the other environments
B. It reduces other variables that can contribute to the results of the study
C. The sample size is too small
D. Some Gerlots may choose not to participate in the study
What is the independent variable in this experiment?
A. Dose of the pill
B. Number of gerlots
C. Number of Gerlots that live in the ocean
D. Number of symptoms present

1. **Why is an experiment the correct method of data collection for this scenario?**
- **b. Rainbow Labs is trying to determine a cause-and-effect relationship.**
In an experiment, researchers manipulate an independent variable (the dosage of the pill, in this case) to observe how it affects a dependent variable (the alleviation of symptoms).
2. **What is the control group in this context?**
- **C. Gerlots that received no dose of the pill.**
The control group consists of participants who do not receive the treatment (pill), allowing researchers to compare the effects of the treatment against a baseline.
3. **Why is it important to choose Gerlots from each of the environments for the control group and experiment groups?**
- **B. It reduces other variables that can contribute to the results of the study.**
Including participants from different environments helps ensure that any observed effects can be attributed more reliably to the dosage of the pill rather than environmental factors.
4. **What is the independent variable in this experiment?**
- **A. Dose of the pill.**
The independent variable is what the researchers manipulate, which in this case is the dosage of the experimental pill given to the Gerlots.

In an experiment, researchers manipulate an independent variable (the dosage of the pill, in this case) to observe how it affects a dependent variable (the alleviation of symptoms).
