Sampling Methods: Techniques, Types, Examples
Sampling method is the process selecting a small group from a larger group of individuals to represent the whole.
Simple Random Sampling
Simple random sampling is a procedure that gives each sampling unit in the population an equal and known non-zero probability of being selected.
Delphi Technique: Definition, History, Characteristics
Delphi technique is an interactive forecasting method used to obtain the opinion of a panel of experts without necessarily bringing them together face to face.
Non-Probability Sampling
In Non-probability, the selection of the sample’s population elements depends on the sampler’s (researcher’s) personal judgment or discretion.
Design Effect: Definition, Examples
The design effect is the ratio of the actual variance of the sample estimate obtained from a particular design to the variance of a simple random sample estimate of the same size.
PPS Sampling: Probability Proportional to Size Sampling Definition, Examples
Probability Proportional to Size(PPC) sampling procedure is a variation on multi-stage sampling where the probability of selecting a PSU is proportional to its size, and an equal number of elements is sampled within each PSU.
