On page 1 of this lesson, you read about the following experiment: 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? (1 point) Responses Rainbow Labs is collecting the opinions of the Gerlots Rainbow Labs is collecting the opinions of the Gerlots Rainbow labs is trying to determine a cause-and-effect relationship Rainbow labs is trying to determine a cause-and-effect relationship Rainbow labs is observing the Gerlots to see how they behave Rainbow labs is observing the Gerlots to see how they behave Rainbow Labs has a really large sample size of data to work with Rainbow Labs has a really large sample size of data to work with Question 2 What is the control group in this context?(1 point) Responses Gerlots that live in the desert Gerlots that live in the desert Gerlots that do not have Fermatisis Gerlots that do not have Fermatisis Gerlots that received a 50 mg dose of the pill Gerlots that received a 50 mg dose of the pill Gerlots that received no dose of the pill Gerlots that received no dose of the pill Question 3 Why is it important to choose Gerlots from each of the environments for the control group and experiment groups?(1 point) Responses It reduces other variables that can contribute to the results of the study It reduces other variables that can contribute to the results of the study The sample size is too small The sample size is too small There are more Gerlots in the desert than in the other environments There are more Gerlots in the desert than in the other environments Some Gerlots may choose not to participate in the study Some Gerlots may choose not to participate in the study Question 4 What is the independent variable in this experiment?(1 point) Responses Total number of Gerlots Total number of Gerlots Number of symptoms present Number of symptoms present Number of Gerlots that live in the ocean Number of Gerlots that live in the ocean Dose of the pill Dose of the pill Skip to navigation

Here are the answers to your questions based on the information provided about the Rainbow Labs experiment:

Question 1: Why is an experiment the correct method of data collection for this scenario?
Response: Rainbow labs is trying to determine a cause-and-effect relationship.
Explanation: Experiments are designed to test hypotheses and establish causal relationships between variables, which is important in evaluating the effectiveness of the treatment pill on Gerlots with Fermatisis.

Question 2: What is the control group in this context?
Response: Gerlots that received no dose of the pill.
Explanation: The control group serves as a baseline to compare the effects of the treatment, and those Gerlots not receiving any medication would allow researchers to assess the pill's impact against the untreated group.

Question 3: Why is it important to choose Gerlots from each of the environments for the control group and experiment groups?
Response: It reduces other variables that can contribute to the results of the study.
Explanation: Including participants from all three environments helps control for environmental factors that might affect the outcome, ensuring that any observed effects can be attributed to the treatment itself rather than external influences.

Question 4: What is the independent variable in this experiment?
Response: Dose of the pill.
Explanation: The independent variable is the factor that is manipulated in the experiment; in this case, it is the different dosages of the treatment pill given to the Gerlots.
