&gt; Once the examiner has an adequate series of charts to evaluate, he will begin the scoring process. This is done most often using a numerical scoring method which evaluates the subject&#x27;s physiological responses to the Relevant and Control questions. The computer polygraph may also use an algorithm developed by the Johns Hopkins University Applied Physics Laboratory or other researchers to score the examination. The examiner can use this algorithm to independently score the examination or for quality control purposes to verify his own determination.<p><a href="http:&#x2F;&#x2F;www.lawofficer.com&#x2F;articles&#x2F;2008&#x2F;12&#x2F;understanding-polygraph.html" rel="nofollow">http:&#x2F;&#x2F;www.lawofficer.com&#x2F;articles&#x2F;2008&#x2F;12&#x2F;understanding-pol...</a><p>If you look closely, you&#x27;ll notice that that&#x27;s a copyright notice for a piece of software evaluating the results.
