With multicultural users it is critical that you know the background of each participant and that you adapt the test for different cultures identify a need. Content bias: content offensive or demeaning, expert judgement to identify. In testing reliability refers to consistency and repeatability. If something is unreliable then it has measurement error. Bathroom scales vary by 1 kg, baby scales in hospitals vary only 20 grams. Baby scales in hospitals are required to be more precise because they (1) weigh less and (2) need to be precise for potential medical intervention. Reliability in measurement means it reflects true rather than chance factors. You are able to count on it as a form of measurement. If to evaluators have different rubrics that would not be a reliable measure. Because our test must accurately reflect our constructs. Obtained scores: total score gathered from the test. Error score: how much of the data can be attributed to error.
