Correct Answer - Option 3 : Unsystematic sampling
Explanation:
There are various types of sampling methods such as:
-
- Simple random sampling
- Systematic sampling
- Stratified sampling
- Probability-proportional-to-size sampling
- Cluster sampling
- Quota sampling
- Minimax sampling
- Accidental sampling
- Voluntary Sampling
- Line-intercept sampling
- Panel sampling
- Snowball sampling
- Theoretical sampling
- Purposive sampling
Hence Option 3 is correct.
Sampling = sampling consists of obtaining information from a larger group or a universe
Systematic sampling= k = population size/sample size
Systematic sampling it is defined as probability sampling method where the researcher chooses elements from a target population by selecting a random starting point and select sample members.
Stratified sampling = stratified sampling is a method of sampling from a population which can be partitioned into subpopulations
Purposive sampling = the main goal of purposive sampling is to focus on particular characteristics of a population that are of interest
