Search. Also known as an accessory tragus or a branchial cleft remnant, ear tags are usually located in front of the ear or on the cheek, and consist of skin and cartilage. Many tags have a narrow stalk (a pedunculated tag), and some pediatricians may tie a string around the tag to intentionally âstrangleâ it.
Validity. The extent to which a test measures what it is supposed to measure. All tests are designed to measure something; hopefully something specific. If the test does indeed measure what it is intended to measure, then we can say that the test is --------.plit-Half Reliability. A measure of consistency where a test is split in two and the scores for each half of the test is compared with one another. If the test is consistent it leads the experimenter to believe that it is most likely measuring the same thing.
However, if the measure seems to be valid at this point, researchers may investigate further in order to determine whether the test is valid and should be used in the future. Essentially, face validity is whether a test seems to measure what it is supposed to measure. It involves taking the test as face value.
