Statistical Planning

Abstract

The Chapter describes main steps in the sample survey design, which include: statement of objectives, definition of target population, defining the sampling frame, formulating the sampling design and determining the sampling Intensity. This is followed by description of some commonly used statistical designs for forest assessments such as simple random sampling, systematic sampling, stratified sampling, double sampling or two phase sampling and two stage sampling (also called cluster sampling) and survey of trees outside forests (tof). Finally, a forest inventory planning check list is presented, which has been by experience found very useful to make sure that nothing important has been forgotten.
