Identify components of the experimental design in a given experiment: use of a control group, use of a placebo, and blinding Question A pharmaceutical company conducted an experiment to test a drug for controlling diabetes. The company enrolled participants for the experiment and divided them into 2 groups. One group received an inert drug and the other group received the diabetes control drug. In the description of the above experiment, determine the experimental group. Select the correct answer below: The group that received the inert drug is the experimental group The group that received the diabetic control drug is the experimental group Both the groups are experimental groups Neither group is an experimental group

1. A pharmaceutical company wants to test the effectiveness of a certain drug on its ability to decrease blood pressure. The company divided the participants into two groups. One group received the drug and the other group received a placebo. All other aspects were the same. The group that received the placebo is the: experimental group. hypothesis group. control group. observation group. variable group.

Dr. Synapse has developed a new medication that they hope will be effective in treating migraine headaches. They expect that it will shorten the duration of a migraine if taken immediately following the first symptoms. To test this, they develop an experiment. They get a large number of volunteers and randomly split them into two groups. Group A is given a placebo pill. Group B is given the new drug. Both groups are instructed to take the pill as soon as they notice symptoms of a migraine and then record the duration of the headache. At the end, they plot the average headache duration for both groups and find that the average migraine duration for group A was shorter than that of group B. Answer the following questions: 1. Identify Dr. Synapse's hypothesis. 2. Identify Dr. Synapse's prediction. 3. Explain what a placebo is and why we had to give group A a placebo rather than giving them nothing and just asking them to record how long their migraines lasted. 4. Which group is the control group? Explain why control groups are necessary. 5. Do the data support the hypothesis? Explain your answer.
