The measure's midpoint observed value for those cases represented in the data element Population for the month.
The observed value is the Measurement Value that is calculated for each case as it is processed through the algorithm and received a measure category assignment = ‘D’ for the measure or stratum.
To determine the Median, sort the case-level cases by their observed values from the highest value to lowest value:
If the total number of Population cases is odd
then Median Observation = the value associated to the middle case
If the total number of Population cases is even
then Median Observation = the average of the values of the two middle cases
NOTE: The calculated Median Observation does not have to be an observed value of the data.
