Researchers were interested in assessing the effects of a new treatment on seasonal affective disorder. Mood was assessed in all participants at three time-points: (1) pre-treatment (0 weeks), (2) after 2 weeks of treatment, and (3) after 4 weeks of treatment.

What is an experiment?
Mental Health A study was performed looking at the effect of physical activity on cognitive function among adults at high risk for Alzheimer's disease. There were 170 eligible subjects randomly assigned to either an exercise intervention (exercise group) or a control intervention (control group). The subjects were followed at 6-month intervals up to 18 months of follow-up. The primary assessment scale was the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog). The results at 18 months of follow-up among participants with mild cognitive impairment are given in the table below. (Let population 1 be the exercise group and population 2 be the control group. Use exercise group control group.)

A researcher studying the effects of environment on mood asks 100 college-age students to sit alone in a waiting room for 15 minutes at the beginning of an experiment. Half of the individuals are assigned to a room with dark blue walls, and the other half are assigned to a room with bright yellow walls. After 15 minutes in the waiting room, each person is brought into the lab and asked to rate their mood on a scale of 1-7. 1. what is the research hypothesis
In a clinical trial, 780 participants suffering from high blood pressure were randomly assigned to one of three groups. Over a one-month period, the first group received a low dosage of an experimental drug, the second group received a high dosage of the drug, and the third group received a placebo. The diastolic blood pressure of each participant was measured at the beginning and at the end of the period and the change in blood pressure was recorded. Identify the experimental units (subjects).

A study is being conducted on the effect of gas price on the number of miles driven in a given month. Residents in two cities, one on the East Coast and one on the West Coast, are randomly selected and asked to complete a questionnaire on the type of car they drive, the number of miles they live from work, the number of children under 18 in their household, their monthly income, and the number of miles they have driven over the past 30 days. (a) List the response variable(s) and the type of measurement scale (nominal/ordinal/interval/ratio) associated with each response variable. (b) Also, state whether this study is an experimental or observational study? Explain in brief the reason for your answer.
