Types of Random Sampling Techniques
Random sampling, also known as probability sampling, is a technique where every member of the population has a known, non-zero chance of being selected. The main types of random sampling techniques are:
- Simple Random Sampling: Every element of the population has an equal probability of selection (e.g., lottery method).
- Systematic Sampling: Elements are selected at a regular interval (every -th element) from a compiled list.
- Stratified Random Sampling: The population is divided into homogeneous subgroups (strata), and samples are drawn from each stratum.
- Cluster Sampling: The population is divided into heterogeneous groups (clusters), and entire clusters are randomly selected.
- Multi-stage Sampling: A complex form of cluster sampling where sampling is carried out in multiple stages.
