Question

Researchers at the Women’s Health Collaborative in Washington, DC, have conducted meta-analyses of studies into women’s attitudes about mammograms. Their findings show a trend since 1995 in attitudes. They wonder if generational differences among research samples produced the trend line. To begin research into this possibility, they plan to sample women of different ages, taking care to avoid surveying women who are related or friends. Using random selection with technology of telephone-dialing software, the researchers survey 400 women between 40 and 54 and also 400 women age 55 or older. The researchers acknowledge that a risk in data collection is that respondents will not want to divulge their ages or will give a false age. To counter this possibility, the research assistants follow a protocol to ask, “ What year were you born?” In recording the answer, a space is provided on the data collection sheet to enter the number of seconds it takes a respondent to answer with a year. Respondents who answer with a year that makes them younger than age 40 are thanked for their participant and the survey ends. Respondents age 40 and older then are asked about their attitudes toward mammograms, and are asked to answer with a rating number.

a. This is an example of experimental research. True OR False

b. The researcher used randomization. True OR False

c. Two groups were compared. True OR False

d. Four groups were compared. True OR False

e. The IV was gender. True OR False

f. The IV was age or generation. True OR False

g.Nonparametric stats test because the IV is nominal. True OR False

h. A t Test or ANOVA could be selected for the stats test. True OR False

I. DV = attitudes True OR False

j. This is an example of observational research. True OR False

Answer 1

A. False ,this is not an experimental research because there is no experiment done in it and also it's using a survey method to collect data .

B. True , the researcher has used random selection of sample .

C. True ,two groups are being compared . One group is younger than 40year and the another group is 40yeara and older .

D. False only two groups were compared . One group is younger than 40year and the another group is 40yeara and older .
