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? - CORRECT 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: - CORRECT 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: - CORRECT 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? - CORRECT 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: -
CORRECT ANSWER-internal consistency reliability
A researcher administers a scale measuring self-confidence and one measuring self-doubt to a
group of subjects and performs a correlational analysis of the results. This is a test of validity
from: - CORRECT ANSWER-divergent validity
A researcher develops a new instrument to measure coping skills and conducts a pilot study
to compare the new tool with an existing tool that measures this concept. This is an example
of evidence of validity from: - CORRECT ANSWER-Convergent validity
A researcher evaluates whether a tool addresses the major elements of the construct being
studied. This helps to ensure: - CORRECT ANSWER-content validity
A researcher studying depression in relation to five predictor variables decides to include five
more variables in the study because the literature reveals that they may also be involved in
depression. Consequently, the researcher will do which of the following? - CORRECT ANSWER-
Use a larger sample size.
"To be considered eligible for the study, subjects had to be older than 21 years of age, hold a
valid state driver's license, and be able to fire a shotgun." This is an example of which of the
following? - CORRECT ANSWER-Sampling criteria
A researcher consented 75 subjects, but 15 dropped out of the study while it was still in
progress. What was the sample attrition rate? - CORRECT ANSWER-20%
A researcher attempted to recruit all 150 of the patients seen in the emergency department in
a three-month period for diverticulitis, but only 120 consented to participate. What is the
sample size? - CORRECT ANSWER-120
