Distractors should be carefully examined when items show large positive D values. When one or more of the distractors looks extremely plausible to the informed reader and when recognition of the correct response depends on some extremely subtle point, it is possible that examinees will be penalized for partial knowledge. Thompson and Levitov (1985) suggested computing reliability estimates for a test scores to determine an item's usefulness to the test as a whole. The authors stated, "The total test reliability is reported first and then each item is removed from the test and the reliability for the test less that item is calculated" (Thompson & Levitov, 1985, p.167). From this the test developer deletes the indicated items so that the test scores have the greatest possible reliability. Developing the perfect test is the unattainable goal for anyone in an evaluative position. Even when guidelines for constructing fair and systematic tests are followed, a plethora of factors may enter into a student's perception of the test items.

Perhaps even more funny is the fact that the drummer Frank Beard never grew one out, despite his suggesting last name. Texas couldn’t contain the music might that is ZZ Top for long. The band continued to released several more albums, all of which were moderately successful. ZZ Top continued to ride the wave of success to get global appeal. Although not at their peak, the next few albums would be the driving force that put the three in range of the top. This includes albums such as Tres Hombres and Rio Grande Mud, which were both great albums that are relevant even today. Their biggest success was still yet to come, however. ZZ Top broke into the music video scene with Eliminator, one of their most popular albums. Music videos at the time were still fairly new, and the MTV network was still fresh in its infancy. Videos for the singles “Legs” and “Sharp Dressed Man” did extremely well in the charts.
