Unit 8 - Stats The study described below is a randomized comparative experiment. Describe the freatment, the freatment group, and the control group. 8. A medical researcher collects data about a certain medicine. She asks 10 patients to take the medicine and another 10 patients to take a placebo (a sugar pil known to have no effect). None of the patients knows which group he or she is in.. At the end of 6 months, the group taking the medicine showed more improvement in their symptoms than the group taking the placebo.

## Step 1<br />In this problem, we are given a scenario where a medical researcher is conducting an experiment to test the effectiveness of a certain medicine. The experiment involves two groups of patients: one group is given the medicine, and the other group is given a placebo.<br /><br />## Step 2<br />The treatment in this experiment is the administration of the medicine. This is the variable that the researcher is manipulating to see if it has an effect on the patients' symptoms.<br /><br />## Step 3<br />The treatment group is the group of patients who are given the medicine. This group is the one that the researcher is testing the effect of the treatment on.<br /><br />## Step 4<br />The control group is the group of patients who are given a placebo. This group is used as a baseline to compare the effects of the treatment. The placebo is a substance that is known to have no effect, so any changes in the control group can be attributed to the placebo effect rather than the treatment itself.<br /><br />## Step 5<br />In this experiment, the treatment group showed more improvement in their symptoms than the control group. This suggests that the medicine is effective in improving the symptoms of the patients.
