a. Convenience
b. Random
c. Stratified
d. Systematic
Explanation:
Types of sampling:
The selection of sample is arbitrary and each member has an equal chance of selection.
This selection does not take probability of selection into account rather focuses on the convenience and proximity of the member for selection.
An ordered system is decided to choose the members for this sample.
This sampling plan divided the population into groups, called clusters. A cluster is then randomly selected from the selected population.
The members of the population are divided into groups, called strata. A random sample is drawn from each strata.
