In your unit readings from the text, you read about three sources of error variance that occur in testing and assessment. These include test construction, test administration, and test scoring and interpretation. Additionally, other sources of error may be suspect. You were also introduced to reliability coefficients, which provide information about these sources of error variance on a test (see Table 5-4). The following reliability coefficients were obtained from studies on a new test, THING, purporting to measure a new construct (that is, Something). Alternate forms of the test were also developed and examined in subsequent studies published in the peer-reviewed journals. The alternate test forms were titled THING 1 and THING 2. (Remember to refer back to your text for information about using and interpreting a coefficient of reliability.) In your post: (Discussion Guidelines) Discussion question instructions will be presented for each question as it is posted. Your discussion answers must be thorough and expansive.
