SOC: The tables that follow report the marital status of 20 respondents in two different apartment complexes.
Read each of the following problems carefully before constructing the fraction and solving for the answer. (HINT: Make sure you have the correct numbers in the numerator and denominator before solving these problems. For example, problem 2.1a asks which "percentage of the respondents at each complex are married" and the denominators will be 20 for these two fractions. On the other hand, problem 2.1d, asks which "percentage of the single respondents live in Complex B" and the denominator for this fraction will be 4 + 6, or 10.)
a. What percentage of the respondents at each complex are married?
b. What is the ratio of single to married respondents at each complex?
c. What proportion of each sample are widowed?
d. What percentage of the single respondents live in Complex B?

SOC: The scores of 15 respondents on four variables are as reported below. These scores were taken from a public opinion survey called the General Social Survey, or the GSS. This data set is used for the computer exercises in this text. Small subsamples from the GSS will be used throughout the text to provide "real" data for problems. For the actual questions and other details, see Appendix G. The numerical codes for the variables are:
a. Construct a frequency distribution for each variable. Include a column for percentages.
b. Construct pie and bar charts to display the distributions of sex, support for gun control, and level of education.

SW: A local youth service agency has begun a sex education program for teenage girls who have been referred by the juvenile courts. The girls were given a 20-item test for general knowledge about sex, contraception, and anatomy and physiology on admission to the program and again after completing the program. The scores of the first 15 girls to complete the program are:
Construct frequency distributions for the pretest and posttest scores. Include a column for percentages. (HINT: There were 20 items on the test, so the maximum range for these scores is 20. If you use 10 class intervals to display these scores, the interval size will be 2. Because there are no scores of 0 or 1 for either test, you may state the first interval as 2-3. To make comparisons easier, both frequency distributions should have the same intervals.)

SOC: Figures 2.9 through 2.11 display trends in crime in the United States over the last two decades. Write a paragraph describing each of these graphs. What similarities and differences can you observe among the three graphs? (For example, do crime rates always change in the same direction?) Note the differences in the vertical axes from chart to chart; for homicide, the axis ranges from 0 to 12, while for burglary and auto theft, the range is from 0 to 1,600. The latter crimes are far more common, and a scale with smaller intervals is needed to display the rates.

PA: A city's Department of Transportation has been keeping track of accidents on a particularly dangerous stretch of highway. Early in the year, the city lowered the speed limit on this highway and increased police patrols. Data on the number of accidents before and after the changes are presented here. Did the changes work? Is the highway safer? Construct a line chart to display these two sets of data (use graphics software if available), and write a paragraph describing the changes.

Problems are labeled with the social science discipline from which they are drawn: SOC is for sociology, SW is for social work, PS is for Political Science, CJ is for Criminal Justice, PA is for Public Administration, and GER is for Gerontology.
PA/CJ: As part of an evaluation of the efficiency of your local police force, you have gathered the following data on police response time to calls for assistance during two different years. (Response times were rounded off to whole minutes.) Convert both frequency distributions into percentages, and construct pie charts and bar charts to display the data. Write a paragraph comparing the changes in response time between the two years.

SOC: Figures 2.9 through 2.11 display trends in crime in the United States over the last two decades. Write a paragraph describing each of these graphs. What similarities and differences can you observe among the three graphs? (For example, do crime rates always change in the same direction?) Note the differences in the vertical axes from chart to chart; for homicide, the axis ranges from 0 to 12, while for burglary and auto theft, the range is from 0 to 1,600. The latter crimes are far more common, and a scale with smaller intervals is needed to display the rates.

PA: A city's Department of Transportation has been keeping track of accidents on a particularly dangerous stretch of highway. Early in the year, the city lowered the speed limit on this highway and increased police patrols. Data on the number of accidents before and after the changes are presented here. Did the changes work? Is the highway safer? Construct a line chart to display these two sets of data (use graphics software if available), and write a paragraph describing the changes.
