1.6 For each research project listed here, identify the variables and classify them in terms of level of measurement and whether they are independent or dependent.
a. For a research project in a political science course, a student collected information for 50 nations. She used infant mortality rates (the number of infant deaths per 100,000 population) as a measure of quality of life and the percentage of all adults who are permitted to vote as a measure of democrati- zation. Her hypothesis was that quality of life is higher in more democratic nations.
b. A highway engineer wonders whether increasing the speed limit on a heavily traveled high- way will result in more accidents. He plans to collect information on traffic volume, number of accidents, and number of fatalities for the six- month periods before and after the speed limit is changed.
c. Students are planning a program to promote “safe sex” and awareness of other health concerns on campus. To measure the effectiveness of the pro- gram, they plan to survey students about their knowledge of safe sex practices before and after the program.
