NURS 5366 MODULE 3 EXAM WITH QUESTIONS
AND 100% VERIFIED ANSWERS
A researcher is investigating the effect of hypnosis on pain during dental
operations. The researcher's study divides participants into two groups: those who
get hypnosis during the operation and those who do not. If the researcher intends to
utilize a t-test for statistical analysis, what is the appropriate technique to assess
pain in this study? - ANSWER numerical pain scale ranging from 0 to 100.
A researcher conducts a series of pilot trials to determine if a measurement tool
generates consistent data. This is an assessment of: - Answer Reliability
A researcher creates a 7-point Likert scale to assess patients' sense of well-being
while undergoing chemotherapy. This test is given to other patients with similar
characteristics in several medical centers. This is done to increase test-retest
reliability.
In a pilot study to help train a group of data collectors who will assess children's
pain using a FACES rating scale, the researcher investigates the reliability of each
data collector's findings. This is an example of what kind of dependability
measure? - ANSWER Inter-rater reliability
A researcher uses Cronbach's alpha coefficient statistical approach to analyze
scores on a paper and pencil instrument with variables at the interval level of data.
This is a test for: - ANSWER: internal consistency and reliability
A researcher administers a self-confidence measure and a self-doubt scale to a
group of subjects, then conducts a correlational analysis on the data. This is a
validity test for: - ANSWER: Divergent validity
