Overpopulation – The Human Explosion Explained
Two-stage cluster sampling involves randomly selecting multiple clusters and choosing certain subjects randomly within each cluster to form the final sample. Two-stage sampling can be seen as a subset of one-stage sampling: sampling certain elements from the created clusters. This sampling method may be used when completing a list of the entire population is difficult as demonstrated in the example above. This is a simple, manual process that can save time and money. In fact, using cluster sampling can be fairly cheap when compared to other methods. That's because there are generally fewer associated costs and expenses because cluster sampling requires choosing selected clusters at random rather than evaluating entire populations. This same process also allows for increasing the sample size.
As a statistician is only choosing from a select group of clusters, they can increase the number of subjects to sample from within that cluster. The primary disadvantage of cluster sampling is that there is a larger sampling error associated with it, making it less precise than other methods of sampling. This is because subjects within a cluster tend to have similar characteristics, meaning that cluster sampling does not include varied demographics of the population. This often results in an overrepresentation or underrepresentation within a cluster, and, therefore, can be a biased sample. For example, say an academic study is being conducted to determine how many employees at investment banks hold MBAs , and of those MBAs, how many are from Ivy League schools.
It would be difficult for the statistician to go to every investment bank and ask every single employee their educational background. To achieve the goal, a statistician can employ cluster sampling. The first step would be to form a cluster of investment banks. Rather than study every investment bank, the statistician can choose to study the top three largest investment banks based on revenue, forming the first cluster. From there, rather than interviewing every employee in all three investment banks, a statistician could form another cluster, which would include employees from only certain departments, for example, sales and trading or mergers and acquisitions.
This method allows the statistician to narrow down the sampling size, making it more efficient and cost-effective, yet still having a varied enough sample to gauge the information being sought. Though both systematic sampling and cluster sampling are forms of random sampling, they arrive at their sample size in completely different ways. Systematic sampling chooses a sample based on fixed intervals in a population whereas cluster sampling creates a cluster from a population. Cluster sampling is better suited for when there are different subsets within a specific population, whereas systematic sampling is better used when the entire list or number of a population is known.
Both, however, are splitting the population into smaller units to sample. For systematic sampling it is important to ensure there are no patterns in the group, otherwise, you risk choosing similar subjects without representing the overall population. For cluster sampling, it is important to ensure that each cluster has similar traits to the whole sample. Cluster sampling is a form of random sampling that separates a population into clusters to create a sample. Further clusters can be created from the initial clusters as well to narrow down a sample. Cluster sampling is best used to study large, spread out populations, where aiming to interview each subject would be costly, time-consuming, and perhaps impossible.
Cluster sampling allows for creating clusters that are a smaller representation of the population being assessed, with similar characteristics. Cluster sampling simply involves dividing the population being studied into smaller groups. These subgroups can be studied or further randomly divided into other subgroups. The primary difference between cluster sampling and stratified sampling is that the clusters created in cluster sampling are heterogeneous whereas the groups for stratified sampling are homogeneous. There are a variety of sampling methods available to statisticians who seek to study information within groups.
Because groups or populations tend to be large, it is very difficult to obtain data from every single subject. To overcome this problem, statisticians use sampling, creating smaller groups that are meant to be representative of the larger population. An important aspect of creating these smaller samples is to ensure they are selected at random and are a true representation of the larger population. Systematic sampling and cluster sampling are two methods that statisticians can use to study populations. Both are forms of random sampling that can be time- and cost-efficient, separating populations into smaller groups for easier analysis. Systematic sampling works best when the entire population is known while cluster sampling works best when the entire population is difficult to gauge.
