A

findings suggest that cholesterol levels influence cardiac blood flow.

62
Q

the sampling criteria for a study are (1)men&women over age 25 years,(2)who have no chronic illness,(3)who can read&write either English or Spanish,&(4)who completed the 9th grade.Why might a researcher broadly define the eligibility or sampling criteria for a study?What type of sample will result from broad eligibility criteria-homogenous or heterogeneous?Which research designs are most consistent w/ broad eligibility criteria?

A
  • to be able to recruit a large sample and/or to increase the generalizability of the study findings.
  • heterogeneous
  • broad sampling criteria are appropriate for descriptive and correlational designs because a range of scores on variables is desirable. the goal of these designs is to accurately represent a phenomenon in a natural setting.
63
Q

the sample critieria for a study are (1)women between the ages 35&45,(2)who have no chronic illness,(3)who are employed,(4)who have completed at least 2 yrs of college,&(5)who are not married or partnered.Why might a researcher narrowly define the eligibility or sampling criteria for a study?What are the challenges that can result from narrow eligibility criteria?Which research designs are most consistent with narrow eligibility criteria?

A
  • to create a homogeneous sample with fewer extraneous characteristics that could influence the study findings.
  • may be difficult to recruit persons who fit the criteria and increase the time required to complete the study.
  • quasi-experimental and experimental designs. in these studies, the researcher wants tight control to increase the credibility of the findings and to assure that any differences that are found are due to intervention or treatment
