Medical study variables Data from a medical study contain values of many variables for each of the people who were the subjects of the study. Here are some of the variables recorded: gender (female or male) age (years) race (Asian, black, white, or other); smoker (yes or no) systolic blood pressure (millimetres of mercury) level of calcium in the blood (micrograms per millilitre).

Identify each as categorical or quantitative.

Where do the young live? Below is a stem plot of the percent of residents aged 25 to 34 in each of the 50 states. As in the stem plot for older residents (page 35), the stems are whole percent and the leaves are tenths of a percent. This time, each stem has been split in two, with values having leaves 0 through4 placed on one stem, and values ending in 5 through 9 placed on another stem.

(a) Why did we split stems?

(b) Utah has the highest percentage of residents aged 25 to 34. What is that percent? Why do you think Utah has an unusually high percentage of residents in this age group?

(c) Describe the shape, center, and spread of the distribution, ignoring Utah.

Fuel efficiency In an earlier example, we examined data on highway gas mileages of the model year 2009 midsize cars. The dot plot below shows the difference (highway 鈥� city) in EPA mileage ratings for each of the 24car models from the earlier example.

(a) Explain what the dot above 6represents.

(b) What does the graph tell us about fuel economy in the city versus on the highway for these car models? Be specific.

At the Census Bureau Web site, you can view detailed data collected by the American Community Survey. The table below includes data for 10 people chosen at random from the more than one million people in households contacted by the survey. 鈥淪chool鈥� gives the highest level of education completed.

The chapter-opening Case Study described research by Teresa Amabile investigating whether external rewards would promote creativity in children鈥檚 artwork. Dr. Amabile conducted another study involving college students, who were divided into two groups using a chance process (like drawing names from a hat). The students in one group were given a list of statements about external reasons

(E) for writing, such as public recognition, making money, or pleasing their parents. Students in the other group were given a list of statements about internal reasons (I) for writing, such as expressing yourself and

enjoying playing with words. Both groups were then instructed to write a poem about laughter.

Each student鈥檚 poem was rated separately by 12different poets using a creativity scale. The 12poets鈥� ratings of each student鈥檚 poem were averaged to obtain an overall creativity score.

A dot-plot of the two groups鈥� creativity scores is shown below. Compare the two distributions. What do you conclude about whether external rewards promote creativity?

A class survey Here is a small part of the data set that describes the students in an AP Statistics class. The data come from anonymous responses to a questionnaire filled out on the first day of class.
