Question

What does the term stability mean in the context of the reliability of a research study?

A.the extent to which researchers obtain the same outcome on repeatedly administering the research instrument

B.the extent to which the different parts of research instruments measure the same research dimensions

C.the equivalence of the research results obtained by different researchers using the same research instruments

D.the method of obtaining the same results using two different research instruments on the same target audience

E.the extent to which different research instruments reveal the same results on different target audiences

Answer 1

Answer: {A}

the extent to which researchers obtain the same outcome on repeatedly administering the research instrument

Explanation: Stability is an aspect of reliability and many researchers report that a highly reliable test indicates that the test is stable over time. The definition of stability given by the Standards for Educational and Psychological Testing is "the extent to which scores on a test are essentially invariant over time". Stability is an aspect of reliability and is assessed by correlating the test scores of a group of individuals with scores on the same test, or an equated test, taken by the same group at a later time’.

Answer 2

A. the extent to which researchers obtain the same outcome on repeatedly administering the research instrument.

Step-by-step explanation:

Stability, in research context, is an aspect of reliability. According to the Standards for Educational and Psychology Testing, stability is "the extent to which scores on a test are essentially invariant over time". From this definition, we can deduct that, if our instrument gives us same results over time, we can say that is reliable, its stability is significant.

This aspect has a huge importance in research, because without reliability, outcomes are not valid to the scientist community.
