/.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

a test of validity from: - 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: - Answer-Convergent validity
/.A researcher evaluates whether a tool addresses the major elements of the construct
being studied. This helps to ensure: - 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? - Answer-Use a larger sample size.
