Introduction Sampling is an essential part of statistics, there are many ways to take samples using SAS. This paper will discuss the different sampling options that are available through the use of PROC SURVEY. PROC SURVEYSELECT is an essential range areas, systematic sampling and stratified systematic unaligned sampling greatly overestimated the population parameters and, therefore, should be used only with extreme caution. Cluster sam pling worked reasonably well. Congalton's concern with bias of systematic designs appears contradictory to Maling's (1989) and Berry and Baker's (1968) Cluster sampling is efficient if measurements within clusters are heterogenous and the cluster means are nearly equal. Systematic sampling is used quite often simply as a convenience. It may actually be better than srs if the population is orderd.

The disadvantages to a stratified SRS include all of the same errors outlied with the SRS, except now we each individual does not necessarily have an equal chance of being chosen. With the grade example, each of the classes at DHS has a differing amount of students, meaning a student in the Junior class may have a higher or lower percent of being chosen than a student in another strata.

Apart from that, the statistical analyses used in the case of cluster sampling are also more complex than the ones used in case of stratified sampling. 4. Systematic sampling: Stratified Random Sampling 15 strata The SRS taken within each group in a stratified random sample need not be of the same size. Other methods Cluster sample: first select clusters at random, and then use all the individuals in the clusters as your sample.

Then I select the cluster by chance (SRS) and I cover the complete cluster. Random, systematic, stratified random, and cluster sampling methods were tested

When setting up a cluster sample, it is important that each cluster is a good representation of the population. This video describes five common methods of sampling in data collection.
