Which of the following scenarios best illustrates a cohort-sequential design? a. Jana wants to understand what predicts student success on the statewide standardized biology competency test. She administers the Biology Interest Survey (BIS) to all of her students at the start of the term and then categorizes students into two groups: those who have taken biology before and those who have not. She then administers an in-class exam at the end of the term. b. Molly’s study examines the benefits of exercise on weight loss. In one group she advocates exercise as well as a new diet program. In the comparison group she only presents the diet program. Those in the comparison group find out that some of Molly’s clients are in an exercise program too, so they form an exercise group on their own. c. Don studies high school students’ concerns about world events during their 9th, 10th, 11th and 12th grade. He surveys the entire 4 grades classes state-wide. He surveys them again every year for four years. d. Melanie is conducting a survey for her thesis that examines administrative policies in middle schools that are intended to decrease bullying. After developing her survey and piloting the instrument with a small group, she then administers the instrument to a sample of 2300 middle-school administrators.

When comparing the northern and southern hemisphere, why are the peak maximum and minimum values of insolation at different times of the year? specifically, why is the peak max of incoming solar radiation in june for the northern hemisphere, but in december for the southern hemisphere? pick the best, most complete answer. because of variations in the incident angle of solar radiation, due to the tilt of earth's axis, the northern hemisphere receives more direct solar radiation in june while the southern hemisphere receives less direct solar radiation. the reverse is true in december. because of earth's tilt, as the earth progresses in its revolution around the sun, the northern hemisphere is relatively closer to the sun in june while the southern hemisphere is relatively farther from the sun. the reverse is true in december. because of earth's elliptical orbit, the northern hemisphere is relatively closer to the sun in june/july while the southern hemisphere is relatively farther from the sun. the reverse is true in december. because of variations in the incident angle of solar radiation and the length of day, due to the tilt of earth's axis, the northern hemisphere receives more direct solar radiation and has longer daylight hours in june while the southern hemisphere receives less direct solar radiation and shorter daylight hours. the reverse is true in december.
