MULTIPLE CHOICE:
1. In experimental and quasi-experimental research, another name for the "treatment" is:
1.Control
2.Randomization
3.Manipulation
4.None of the above

Sampling may be defined as:
1.Measuring study variables
2.Selecting people for a study
3.Identifying criteria for subjects
4.Selecting a study design

The purpose of randomization is:
1.Ensure representativeness of target population
2.Detect inconsistencies in the sampling procedure
3.Evaluate the sampling criteria
4.Assess the adequacy of the research design

4.You are shopping in the mall and are approached by individuals who identify themselves as researchers for a local food chain. They ask you to participate in their study by answering a few questions. As a subject in this survey, you were selected by which method of sampling?
1.Random sampling
2.Systematic sampling
3.Purposive sampling
4.Convenience sampling

5. You want to obtain a sample of individuals who are HIV positive. Which of the following sampling methods would be the MOST effective way to obtain an adequate sample?
1.Accidental sampling
2.Cluster sampling
3.Network sampling
4.Purposive sampling

MATCHING: Indicate if proposed study listed below would be exempt from review, be an expedited review, or require a full board review.
Review Status
Proposed Study
a. Exempt
b. Expedited
c. Full Review Board

6. Study on 25 year old female Where blood samples of 5 cc Taken 3 times per week over 6 weeks

7 Review of charts of childbirth Experience from 1985-1995

8.Behavior modification study with Patients hospitalized on an acute Care psychiatric unit

MULTIPLE CHOICE:
9. The type of nonprobability sampling which is most likely to yield a representative sample is:
1.Convenience sampling
2.Network sampling
3.Quota sampling
4.Purposive sampling

10 In selecting an instrument for a research project, the primary consideration is:
1.Whether the instrument adequately addresses the conceptual meaning is the phenomena of interest
2. Whether the instrument is familiar to the researcher
3. Whether the instrument is costly
4. Whether the instrument has been used by numerous other researchers

11. Which of the following would most likely yield the largest response rate?
1.Telephone interview
2.Mailed questionnaire
3.Questionnaire given out by the employer
4.Mailed survey

12.In order to use the results from a questionnaire for a research study, you must have a response rate of:
1.30%
2.50%
3.65%
4.90%

TRUE/FALSE QUESTIONS: DEFEND YOUR ANSWER-WRITE IT CORRECTLY
13.An instrument can be reliable but not be a valid instrument.
14.In a factorial design which is a 2 x 2, this means there are two
levels of each of the dependent variables.
15.The Hawthorne effect threatens the internal validity of a research
study.
16.The aim of the research in a phenomenological research study is to
describe an experience as it is lived by the person.
17.Mortality in a research study is a threat to the internal validity of
the study.

18.External validity is the degree to which the results of the study can
be generalized to settings or samples other than the one studied.

19.The grounded theory approach is applied to qualitative data after
they have been gathered in the field.

DEFINE THE FOLLOWING AND GIVE EXAMPLE:
20. Validity:
21. Reliability:
22. Ethnography:
23. Phenomenology:
24. Grounded Theory
25. Ethnoscience:
26. Hermeneutics:
