Answer to Question 1

ANS: C
Stability, one aspect of reliability, is concerned with the consistency of repeated measures.
Content analysis can contribute to establishing validity, not reliability.
Level of measurement is not associated with consistency.
Equivalence, another aspect of reliability, focuses on consistency between two or more observers measuring the same event. Homogeneity, the third indication of reliability in research, examines the extent to which all items in an instrument consistently measure the construct of interest.
Validity refers to the fact that the instrument measures what it says it will measure.

Answer to Question 2

ANS: A
Test-retest reliability assumes the factor to be measured remains the same at the two testing times and that any change in the value or score is a consequence of random error.
The accuracy of an instrument is not measured by test-retest reliability.
A much higher correlation would be required to consider good test-retest reliability.
The amount of time between measurements is variable and depends on what kind of measure it is.
