Question 1

Which of the following refers to 'the use of one technique to measure different things should yield different results'?

Accepted Answer

Discrimination in the context of measurement and assessment refers to the ability of a technique or instrument to distinguish between different constructs or variables. This means that if a method is used to measure different things, it should yield different results, indicating it can discriminate between the constructs being measured.

Question 2

Which of the following types of reliability asks the question 'when the same instrument is administered at least twice to the same group,are the results or scores the same or stable)'?

Accepted Answer

Test-retest reliability measures the consistency of test results when the same test is administered to the same group of people under similar conditions at two different points in time. This type of reliability is concerned with the stability of scores over time.

Question 3

Which of the following involves the use of multiple methods to measure multiple traits?

Accepted Answer

Convergent-discriminant validation involves using multiple methods to measure multiple traits to ensure that the measures that are supposed to be related are indeed related (convergent validity) and those that are supposed to be unrelated are indeed unrelated (discriminant validity). This approach helps in assessing the validity of the constructs being measured.

Question 4

Which of the following types of reliability asks the question 'does the administration of a disguised or alternate version of the same instrument to the same group result in the same stable)score's?

Accepted Answer

Multiple forms reliability involves administering different versions of an instrument (which are supposed to measure the same construct) to the same group of individuals. The aim is to determine if both versions produce similar results, indicating that the instrument is reliably measuring what it is supposed to, regardless of the specific form used.

Question 5

Which of the following refers to the use of multiple measures of the same concept?

Accepted Answer

Triangulation refers to the method of using multiple measures or data sources to investigate the same phenomenon, enhancing the credibility and validity of the research findings.

Question 6

Which of the following is another term for invalidity,and sources of potential error or invalidity are ever present,even in some of the best research?

Accepted Answer

Error is another term for invalidity, and it refers to inaccuracies or mistakes that can affect the validity of research findings.

Question 7

Which of the following types of validity asks the question 'does the instrument work in practically distinguishing current status concurrent validity)or future outcomes predictive validity)of the concept being measured'?

Accepted Answer

Pragmatic validity focuses on whether an instrument is practical in distinguishing current status (concurrent validity) or future outcomes (predictive validity) of the concept being measured, emphasizing its usefulness in real-world applications.

Question 8

Which of the following types of validity asks the question 'does the instrument in fact measure the concept in question'?

Accepted Answer

Construct validity is concerned with whether the instrument actually measures the theoretical construct it claims to measure. It addresses the question of whether the instrument truly captures the concept it is intended to measure, making it the correct answer.

Question 9

Which of the following refers to the different measures of the same concept should yield similar results,whereas the same measure of different concepts should yield differ results?

Accepted Answer

Convergent-discriminant validity involves two key principles: measures that should be related (convergent validity) are, in fact, observed to be related, and measures that should not be related (discriminant validity) are observed not to be related. This ensures that the measure accurately captures the concept it is intended to measure, distinguishing it from other, unrelated concepts.

Question 10

Which of the following are considered valid reasons for the lack of validation studies in criminal justice?

Accepted Answer

All of the above options (unfavorable climate, interjurisdictional disputes, and tradition) are considered valid reasons for the lack of validation studies in criminal justice. These factors contribute to challenges in conducting and implementing research in this field.

Question 11

Which of the following refers to the accuracy of the scale or measurement in tapping the correct concept or construct?

Accepted Answer

Construct validity refers to the extent to which a test measures the concept or construct it is intended to measure. It assesses whether the test is actually tapping into the theoretical construct it claims to be measuring.

Question 12

Which of the following refers to the accuracy of the measuring instrument in predicting current status or future status?

Accepted Answer

Pragmatic validity refers to the accuracy of a measuring instrument in predicting current status or future outcomes, focusing on the practical relevance and applicability of the measurement in real-world settings.

Question 13

Which of the following refers to 'the use of different techniques to measure the same concept should yield the same findings'?

Accepted Answer

Convergence refers to the idea that different methods or measures used to assess the same concept should produce similar results. This concept is often used in research to validate the reliability and validity of measurement tools.

Question 14

Which of the following refers to the accuracy of measurement;does my measuring instrument in fact measure what it claims to measure?

Accepted Answer

Validity refers to whether an instrument measures what it is supposed to measure. It assesses the accuracy of the purpose of the measurement, not just the numerical accuracy.

Question 15

Which of the following refers to the accuracy of individual items in a scale in measuring the concept being measured?

Accepted Answer

Content validity refers to how accurately an assessment or measurement tool taps into the various aspects of the specific construct in question. It ensures that the measure includes an appropriate range of items that reflect the concept being measured.

Question 16

Which of the following types of validity asks the question 'does each item or the content of the instrument measure the concept in question'?

Accepted Answer

Content validity refers to the extent to which a measure represents all facets of a given social construct. In this case, it assesses whether each item or the content of the instrument accurately measures the concept it is intended to measure.

Question 17

Which of the following refers to consistency and/or stability of a measuring instrument?

Accepted Answer

Reliability refers to the consistency and stability of a measuring instrument over time, indicating that the same results would be obtained on repeated applications of the instrument.

Question 18

Which of the following types of reliability asks the question 'in the administration of the instrument to one group at one time,are separate halves of the instrument similar in response are they consistent)'?

Accepted Answer

Split-half reliability assesses the internal consistency of a test by comparing the results of two halves of a test. This method checks if both halves of an instrument yield similar and consistent results when administered to the same group at one time.

Question 19

Which of the following types of validity asks the question 'does the measuring instrument appear "at face value" to be measuring what I am attempting to measure'?

Accepted Answer

Face validity refers to the extent to which a test is subjectively viewed as covering the concept it purports to measure. It is about whether the test looks like it measures what it is supposed to measure, at face value, to laypeople or those taking the test, rather than to experts in test construction.

Question 20

Which of the following refers to the accuracy of the instrument in measuring that which is intended?

Accepted Answer

Face validity refers to the extent to which a test appears to measure what it is supposed to measure, based on subjective judgment.
