Systematic sampling involves selecting every nth individual from a list or population. If there is periodicity in the population (i.e. a repeating pattern or cycle), then the sample may not be representative of the population and may skew towards certain characteristics. For example, if the population had a repeating pattern of every 10th person having a certain characteristic, then a systematic sample selecting every 10th person would over-represent that characteristic. The other sampling techniques (simple random, stratified, cluster, and double) do not involve selecting individuals based on a specific pattern and are less likely to be affected by periodicity.
