Question

Answer

Sampling may be random or non-random.
Non-random sampling does not involve random selection.
In this probability of selection are not specified for the individual in the population.
There are five types of non-probability sampling technique:
Quota sampling
Convenience sampling
Purposive sampling
Self selection sampling
Snowball sampling
So, they are all forms of non-random sampling is correct.

Answer

Non-random sampling is a method used in research to select a sample from a larger population in a non-random manner. It involves selecting individuals or units based on certain criteria, rather than using a random selection process. This type of sampling is often used when it is not feasible or practical to select a random sample.

There are several types of non-random sampling methods, including snowball sampling, convenience sampling, and quota sampling. These methods differ in their approach and the criteria used to select the sample. However, all of these methods are considered forms of non-random sampling.

Snowball sampling is a method where initial participants are selected based on specific criteria, and then they are asked to refer or nominate other individuals who meet the criteria. This method is often used in studies where the target population is difficult to reach or identify, such as hidden populations or marginalized communities. It relies on the connections and networks of the initial participants to recruit additional participants.

Convenience sampling is a method where individuals or units are selected based on their availability and accessibility. This method is often used when it is convenient or practical to select participants who are easily accessible or readily available. For example, a researcher may choose to conduct a survey by approaching individuals in a shopping mall or on a university campus.

Quota sampling is a method where the sample is selected to match certain characteristics or quotas of the population. The researcher identifies specific characteristics or criteria that are relevant to the study and then selects individuals to meet those quotas. For example, if a study aims to understand the opinions of different age groups, the researcher may select participants in proportion to the age distribution in the population.

The correct answer is option 'D' because all of the mentioned methods (snowball sampling, convenience sampling, and quota sampling) are forms of non-random sampling. Each method has its own advantages and limitations, and researchers need to carefully consider the appropriateness and potential biases associated with each method when selecting a sampling strategy for their study.
