Sampling Methods For Research Papers
Systematic Clustering Here the selection of elements is systematic and not random except the first element.
Elements of a sample are chosen at regular intervals of population.
Clusters are identified using details such as age, sex, location etc.
Cluster sampling can be done in following ways:· Single Stage Cluster Sampling Entire cluster is selected randomly for sampling.
All the elements of the cluster are used for sampling.
Number of elements in the sample is the sample size.
The difference lies between the above two is whether the sample selection is based on randomization or not.
Non-Probability Sampling It does not rely on randomization.
This technique is more reliant on the researcher’s ability to select elements for a sample.
