The United States census is an example of a huge descriptive research project that uses the entire population as the sample. What are some of the limitations of generalizing census findings back to the entire population? (Select all that apply.)
 
  a. Although all homes must fill out a census report, the homeless population often cannot be accessed, surveyed, and counted, so the homeless population is underrepresented in the findings.
  b. Persons whose primary language is something other than English or Spanish, and who do not speak either language, are more likely to be missed in the census.
  c. The survey method of data collection relies on self-report; some misrepresentation or error is inevitable.
  d. The population changes continuously, and the one described in the census isn't very much like the population on the day the results are published.
  e. Persons in the United States who are no longer here legally but plan to stay do not fill out a report.

Question 2

A researcher has just completed a study demonstrating the effectiveness of three daily servings of freshly pressed tomato juice for prevention of cancers of the gastrointestinal tract.
 
  The results were statistically significant at the p <.01 level. During interpretation, which of the following will the researcher employ? (Select all that apply.)
  a. Examination of the results, in comparison with similar literature about fresh tomatoes and cancer, to decide whether the sum of all knowledge constitutes sufficient evidence for widespread generalization
  b. Exploration of the clinical significance of the findings, as opposed to the statistical significance
  c. Initiation of discussions with manufacturers of juice machines, so as to take advantage of the anticipated increase in sales
  d. Formation of some sort of conclusions, relative to the study findings and related literature
  e. Promulgation of the results to the popular media, so that as many people as possible in the world can advantage themselves of the intervention
  f. Recommendations for further studies on fresh tomato juice and its apparent effects on health
  g. Consideration of implications related to nursing's body of knowledge

Answer to Question 1

ANS: A, B, C, E
Limitations are restrictions or problems in a study that may decrease the generalizability of the findings. All studies have limitations, and these might be theoretical and/or methodological in nature. Theoretical limitations are weaknesses in a study framework and conceptual and operational definitions of variables that restrict the abstract generalization of the findings. Methodological limitations are factors in the study design that can limit the credibility of the findings and restrict the population to which the findings can be generalized.

Answer to Question 2

ANS: A, B, D, F, G
The process of interpreting research outcomes for quantitative, outcomes, and intervention studies includes the following: (1) examining study evidence, (2) determining findings, (3) forming conclusions, (4) identifying limitations, (5) generalizing the findings, (6) considering implications for practice, and (7) suggesting further studies.
