5. When to use a second factor Aa Aa Dr. Diane Gold and her colleagues study how rotating shift work (switching back and forth between the night shift and the day shift, for example) contributes to disrupted sleep cycles, accidents, and nodding off at work. Suppose you are studying a group of police officers to see whether different circadian types are impacted differently by working particular rotations. Circadian types include larks, who are most active in the early morning; hummingbirds,...

5. Presenting means in graphs Aa Aa Suppose you randomly decide whether to administer Treatment A or Treatment B to each of 120 volunteers, such that 40 female volunteers received Treatment A, 20 female volunteers received Treatment B, 20 male volunteers received Treatment A, and 40 male volunteers received Treatment B. Treatments A and B are two different doses of the same drug intended to improve memory. After volunteers receive their treatment, they take a memory test and are given...

6. Creating a bar graph and Benford's Law Aa Aa Here's an interesting exercise: Write down all the numbers you see on the front page of your college newspaper (excluding the page number). Calculate the proportion of numbers beginning with 1 and the proportion of numbers beginning with 4. Which proportion is greater? Your intuition may suggest that you are equally likely to find both kinds of numbers, so the proportions should be roughly the same. However, more often than...
