Exam 15: Reliability and Validity

An ear temperature probe that consistently reports body temperature at a degree lower than the patient's actual temperature has what type of reliability or validity problem?

When the nurse researcher demonstrates that an instrument is highly reliable, which type of error is reduced?

A nurse researcher assesses the degree to which individual items on a scale cluster together around multiple dimensions using what?

A nurse researcher describes an instrument that is administered repeatedly and obtains the same results as having what?

Which measures used to test reliability are specific for homogeneity? (Select all that apply.)

The reliability coefficient of a new instrument is established at 0.86. The nurse researcher should interpret this finding to mean what?

A newly developed instrument is found to have a Cronbach's alpha of 0.82. The nurse researcher interprets this to mean what?

A nurse researcher would want to use a Cronbach's alpha coefficient to establish the internal consistency of an instrument in which case?

What is the significance of concurrent validity to a nurse researcher?

What property is established when the results of two separately administered tests that measure the same domain or concept are highly correlated?

What type of validity is demonstrated by examining the extent to which a passing grade in a nursing course is correlated with passing the registered nurse licensure examination?

A nurse researcher would want to use a Kuder-Richardson (KR-20) coefficient to establish the internal consistency of an instrument in which case?
