Systematic sampling is low risk, controllable and easy, but this statistical sampling method could lead to sampling errors and data manipulation.

PPS Systematic Sampling If you specify the option METHOD=PPS_SYS, PROC SURVEYSELECT selects units by systematic random sampling with probability proportional to size. Systematic sampling selects units ...

Systematic random sampling controls the distribution of the sample by spreading it throughout the sampling frame or stratum at equal intervals, thus providing implicit stratification. You can use the ...

The stratified random sample is always at least as accurate on the average as the random sample and its relative efficiency is a monotone increasing function of the size of the sample. No general ...

Systematic sampling, the classical approach to the estimation of areas by point-counting techniques, is compared to stratified random sampling and to systematic sampling with multiple random starts.
