1- The best way to conceptualize 'homelessness' is to ask people how much money they have in their bank accounts.
2- Social science researchers use the snowball sampling technique for the examination of populations living in cold weather climates.
3- Researchers want to get a representative sample -- which has all the features of the population from which it came -- so that they can produce highly accurate generalizations about the entire population.
4- Reliability and validity are desirable aspects of scientific measurement, and they tie the unobservable ideas of researchers to specific actions in the visible world.
5- Deductive research produces 'better' results because the researcher can find the results that (s)he is looking for more quickly this way.
6- Fiana is planning a research project that will involve interviewing student athletes at NMSU. She should contact NMSU's Institutional review Board (IRB) only if she needs help figuring out which student athletes will be included in her sample.
7- When we talk about operationalization, we are talking about linking conceptual definitions to a specific set of measurement procedures.
8- When Marjorie MacDonald and Nancy E. Wright studied cigarette smoking among women, they used data from a survey carried out with students in secondary schools in British Columbia, Canada in 1995. Since the girls who took that survey are now in their 30's, we can generalize the findings of MacDonald and Wright's study to help us understand why middle-aged women choose to smoke.
9- Carl Mazza's article on the effects of a parenting program on urban African-American adolescent fathers reports that young father were more successful -- that is, they made significant gains in employment, vocational planning, feeling positive about their current relationships with their children, using birth control, begin able to plan for the future, and increasing their number of close friends -- when they attended biweekly parenting classes and met with a social worker weekly. Since this study only looked at one participial parenting program, we can't really generalize the findings.
10- Leading questions help researchers get the responses that they are looking for and are a good way to do scientific research that advances our understanding of human behavior.
11- Jenny is interested in studying attitudes on abortion, but is unsure how she would like to approach the topic. She is considering surveys and interviews as possible options. What costs would Jenny face if she chose one approach versus the other? How would data collected via open-ended interview questions differ from data collected via closed-ended survey questions?
12- Calvin is interested in the relationship between race, gender, and voter support of presidential candidates. As he begins to review the literature to understand the research that has already been done on this topic, what should Calvin do to ensure he is looking at reliable sources of information? How much, for example, should he rely on newspaper articles, peer-reviewed journal articles, television programs, versus library books? Explain how social science researchers evaluate whether sources of information are reliable.
13- Tanveer is planning a research project for which he wants to use random-digit dialing. What are some of the advantages and disadvantages to this approach, and who might be left out if Tanveer uses random-digit dialing?
14- Ricardo is interested in studying the role of alcohol use on student academic performance. Specifically, he wants to know if high levels of alcohol use have a negative effect on grades. He has asked for your advice about the best way to study this research question. What are some good options, and which would you recommend if he asked for your advice? Why?
