Convenient : Drawn from a conveniently available pool.Random : All the options into a hat and drawn some of them.Systematic : Every kth element is taken. Cluster : Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified : Also divides the population into groups.
