31  Degrees of freedom associated with a sampling round () for all other cases
  Where individual or within-strata composite samples were used, work out the degrees of freedom ( to use in equation 66 for a given sampling round, using the following equation:
  equation 68

where:
 is an identifier for the stratum.
H is the number of strata for the CEA.
 is the relative area of the CEA covered by stratum h in the CEA, expressed as a proportion of the total CEA area.
 is the sampling variance of the mean soil organic carbon for each stratum h in the CEA in (tonnes of soil organic carbon per hectare)2, worked out using equation 59
 is the number of samples for each stratum h in the CEA (either within-strata composites samples or individual samples as appropriate).
Note 1: Equation 68 is a simplified equation using the condition that  The original version of the equation is:
Note 2: Where a CEA contains three strata, equation 68 written in its expanded form, where the subscripts 1, 2, and 3 are used to denote values for stratum 1, stratum 2, and stratum 3, respectively takes the following form:
