Question

Are you in agreement with the following statements? If so, give reasons:
(1) Validity is more critical to measurement than reliability.
(2) Stability and equivalence aspects of reliability essentially mean the same thing.
(3) Content validity is the most difficult type of validity to determine.
(4) There is no difference between concept development and concept specification.
(5) Reliable measurement is necessarily a valid measurement,
​

Answer 1

Answer:

yes i am agree with some of the statements

Answer 2

The agreeability of given statements are as follows.

1. The statement "Validity is more critical to measurement than reliability" is agreeable.

• Validity refers to the extent to which a test measures what we actually wish to measure.
• The reliability of a measurement instrument is the extent to which it yields consistent, reproducible estimates of what is assumed to be an underlying true score.

2. The statement "Stability and equivalence aspects of reliability essentially mean the same thing" is not agreeable.

• The stability of an instrument is described as the degree to which similar results are obtained on separate occasions.
• Equivalence is a notion of two measures being qualitatively similar.

3.The statement "Content validity is the most difficult type of validity to determine" is agreeable.

• Content validity assesses whether a test is representative of all aspects of the construct.
• Hence to produce valid results, the measurement method must cover all relevant parts of the subject it aims to measure.

4. The statement "There is no difference between concept development and concept specification" is not agreeable.

• Concept development is a process of developing ideas to solve specified design problems.
• Concept specification refers to a set of documented requirements to be satisfied by a material, design, product, or service.

5. The statement "Reliable measurement is necessarily a valid measurement" is not agreeable.

• Reliable measurement refers to how consistently a method measures something.
• Valid measurement refers to how accurately a method measures what it is intended to measure.
