Fanie, For starters you may want to read about "support" or the "volume-variance relationship" to get a feel for what is going on. A freebie on this may be found at http://uk.geocities.com/drisobelclark/practica.html in Isobel Clark's 1979 Practical Geostatistics chapter 3 titled "The Volume-Variance Relationship". In essence larger samples can be expected to have smaller variances.
