          |  Key QA Questions |   
          | Most 
              QA schemes in QAPonline are based around one question - the Key 
              QA Question - that is used to generate the statistical assessment 
              of performance. The question is usually identified by the  icon. It is used to summaries one performance by 
              Levi 
                Jenning SD from the mean formats or Z score formatsthe

          | In 
            some schemes, the Key QA question is a numeric response e.g. What 
            is the % normal forms for sperm morphology or what is the % fragmentation 
            of an embryo? |   
          | In 
            others is may be calculated or a summation type reply. For instance, 
            in the embryo QA schemes, one cannot measure embryo quality. In such 
            cases, a series of observations are made each with 2 or more options. 
            Each option is allocated a weighting and the sum or multiplication 
            of the observations can be converted into a numeric value. The value 
            may reflect the quality of the embryo but is been generated purely 
            for the purpose of exploring the participants observational skills. 
            It may or may not have any direct correlation to say pregnancy. |
