Sampling in Forest Inventory and its Importance
This is because of the fact that the populations to be assessed for the purpose of say assessment of trees for volume table or of defect or for estimation of enstruation parameters in plantation are usually too large for 100% enumeration to be carried out.Jul 5, 2022
What is the main purpose of sampling?
The aim of sampling is to approximate a larger population on characteristics relevant to the research question, to be representative so that researchers can make inferences about the larger population.
