Question 1
pts
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?
numerical pain scale with a range from 0 to 100
pain scale where the participants report their pain as: none, some, intense
patient report of presence or absence of pain
p. 411
Question 2
pts
A researcher performs a series of pilot studies to evaluate whether a measurement tool
produces consistent results. This is an evaluation of:
Validity
Accuracy
Reliability
Readability
, page 370
Question 3
pts
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:
Decrease mono-operation bias
increase interrater reliability
strengthen the operational definition of the constructs
improve the test-retest reliability
page 370
Question 4
pts
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?
Interrater reliability
Test-retest reliability
alternate forms reliability
