Systematic Sampling | select some starting point then select ever 'k'th element in the population |
Convenience Sampling | use results that are easy to get |
Stratified Sampling | subdivide the population into at least two different subgroups that share the same characteristics, then draw a sample from each subgroup (or stratum) |
Cluster Sampling | divide the population area into sections (or clusters); randomly select some of those clusters; choose all members from selected clusters |
