Which sampling method involves selecting a fixed number of subjects from a population at regular intervals?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: B
Explanation:

Systematic sampling involves selecting a fixed number of subjects from a population at regular intervals.

In stratified sampling, the population is divided into strata based on:

  1. Age

  2. Gender

  3. Income

  4. All of the above


Correct Option: D
Explanation:

In stratified sampling, the population is divided into strata based on age, gender, income, or any other relevant characteristic.

Which sampling method is used when the population is very large and it is not possible to select every member?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: D
Explanation:

Cluster sampling is used when the population is very large and it is not possible to select every member.

In convenience sampling, the subjects are selected based on:

  1. Availability

  2. Convenience

  3. Proximity

  4. All of the above


Correct Option: D
Explanation:

In convenience sampling, the subjects are selected based on availability, convenience, or proximity.

Which sampling method is used when the researcher wants to obtain in-depth information from a small number of subjects?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Purposive Sampling


Correct Option: D
Explanation:

Purposive sampling is used when the researcher wants to obtain in-depth information from a small number of subjects.

The probability of selecting any member of the population is the same in:

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: A
Explanation:

In simple random sampling, the probability of selecting any member of the population is the same.

Which sampling method is used when the population is divided into strata and a simple random sample is selected from each stratum?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: C
Explanation:

In stratified sampling, the population is divided into strata and a simple random sample is selected from each stratum.

In cluster sampling, the sampling units are:

  1. Individuals

  2. Groups

  3. Organizations

  4. All of the above


Correct Option: B
Explanation:

In cluster sampling, the sampling units are groups.

Which sampling method is used when the researcher wants to obtain a representative sample of the population?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: A
Explanation:

Simple random sampling is used when the researcher wants to obtain a representative sample of the population.
