Simple random sampling vs cluster sampling
WebbIn simple random sampling, the inclusion probabilities are equal for all population units. The advantage of this is simple and straightforward statistical inference. With equal inclusion probabilities the unweighted sample mean is an unbiased estimator of the spatial mean, i.e., the sampling design is self-weighting.

WebbIn two-stage sampling, four times a PSU is selected by ppswr and ten SSUs (points) are selected per PSU draw by simple random sampling. The variance of the 10,000 means with two-stage cluster random sampling equals 179.6 (g kg -1) 2. This is considerably larger than with simple random sampling: 56.3 (g kg -1) 2.

I am self-studying some data clustering algorithms recently to solve a problem at work. Sometimes my data set is too big to perform k-means so I take a shortcut: (1) first randomly sample, without replacement, from the data set, then (2) perform k-means on the random sample, finally (3) assign the original data to the closest …
WebbSimple random sampling differs from stratified sampling as the selection occurs from the total population, regardless of shared characteristics. Where researchers apply their own reasoning for stratifying the population, leading to potential bias, there is no input from researchers in simple random sampling. Cluster sampling
WebbSimple random sampling is both simple and random. That means that within a group or subgroup, each member of the population has an equal chance of being selected as a respondent.
