The method described is the systematic sampling method, where the elements are selected on a predecided systematic basis using a fixed interval. This is a type of probability sampling. Quota sampling involves selecting a sample with specific proportions of different segments, stratified sampling involves dividing the population into subgroups and selecting samples from each subgroup, and cluster sampling involves dividing the population into clusters and randomly selecting a few clusters for sampling.
