MODULE 3 QUIZ NURS 5366 SCORE: 100 OUT OF 100 |
QUESTIONS AND ANSWERS | 100% CORRECT
A researcher is studying the effect of hypnosis on pain experienced during
dental procedures. The researcher's study has two groups: those who receive
hypnosis during the procedure and those who receive no hypnosis. If the
researcher plans to use a t-test for the statistical analysis, which would be the
best way to measure pain for this study? Answer - numerical pain scale with a
range from 0 to 100
A researcher performs a series of pilot studies to evaluate whether a
measurement tool produces consistent results. This is an evaluation of:
Answer - Reliability
A researcher develops a 7-point Likert scale to evaluate feelings of well-being in
patients who are undergoing chemotherapy. The researcher administers this
measure to other, similar patients in several medical centers. This is done in
order to: Answer - improve the test-retest reliability
In a pilot study to help train a group of data collectors who will evaluate
children's pain using a FACES rating scale, the researcher examines the
reliability of the scores of each data collector. This is an example of which type
of reliability measure? Answer - Interrater reliability
A researcher evaluates scores of a paper and pencil instrument with variables
at the interval level of data using the Cronbach's alpha coefficient statistical
procedure. This is a test of: Answer - internal consistency reliability
