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
