When many installments have been completed, the Annual Key Report looks a bit more interesting.
When all the installments in a year have been completed by at least one staff in each month, the Key Summary report will document the number for SD units from the mean for each installment. The numbers 1 and 2 represent the number of installments at any point from the mean. In this case, the 2006 Embryo Fragmentation report [HEC2006] indicates that the clinics mean estimates for % embryo fragmentation were all within 1 SD from the mean and importantly were scattered both above and below the mean. You can select any year from the year menu bar at the top of the report. You can remove the menu to print the report [Remove Menu] and you can expand the report to document each installment that was used to create it [Expand].
