the researcher plans to use a t-test for the statistical analysis, which would

be the best way to measure pain for this study?

pain scale where the participants report their pain as: none, some, intense

patient report of presence or absence of pain

numerical pain scale with a range from 0 to 100

Question 3

5 / 5 pts

A researcher develops a 7-point Likert scale to evaluate feelings of wellbeing 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:

increase interrater reliability

 1 / 2

strengthen the operational definition of the constructs

improve the test-retest reliability

Decrease mono-operation bias

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?

Test-retest reliability

Internal consistency reliability

Interrater reliability

alternate forms 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:
