Exam 9: Validity, Reliability, and Triangulated Strategies

Traditionally, little professional prestige has been attached to research involving replication in criminal justice.

Reliability asks, "Does my measuring instrument in fact measure that which I am attempting to measure?"

_________________ is the use of multiple methods to measure the same phenomenon.

_________________ is a type of reliability in which alternate forms of the instrument are administered to the same group.

Questions of validity and reliability are applicable to quantitative studies and are of less concern in qualitative studies.

The split half technique eliminates testing effects as well as some other factors of internal invalidity.

What is the importance of being concerned about issues of validity and reliability in criminal justice research? What are some reasons for the lack of validation studies in criminal justice?

The split half technique was described in the text as a disguised test-retest method.

The type of validity that asks, "Does it work?" is called:

_________________ is concerned with the stability and consistency of measurement.

In the ADAM Program prisoners are forced to supply urine specimens in order to test for drug usage.

Asking whether each element measures the concept in question describes:

_________________ validity is concerned with whether each element or question measures the concept in question.

Criminal justice researchers agree that official statistics are a valid criterion with which to compare self-admission reports.

In requiring arrestees to answer questions regarding drug usage the ADAM program is a potential violation of due process.

_________________ asks the question, "Does my measuring instrument in fact measure what it claims to measure?"

_________________ validity asks whether the instrument in question does, in fact, measure what it has been designated to measure.

Convergent validation suggests that the same measure of different things should yield different results.

Epstein used the term, "phantom army of addicts," to refer to:

_________________ is a type of reliability in which only one test is administered to one group at one time and the halves intercorrelated.
