Which sampling technique involves randomly selecting a certain number of participants from a population?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: A
Explanation:

Simple random sampling is a probability sampling technique where each member of the population has an equal chance of being selected.

In systematic sampling, the researcher selects participants based on a fixed interval from a list or frame.

  1. True

  2. False


Correct Option: A
Explanation:

Systematic sampling is a probability sampling technique where participants are selected at regular intervals from a list or frame.

Stratified sampling involves dividing the population into subgroups and selecting participants from each subgroup.

  1. True

  2. False


Correct Option: A
Explanation:

Stratified sampling is a probability sampling technique where the population is divided into subgroups, and participants are selected from each subgroup.

Cluster sampling is a probability sampling technique where the researcher selects a group of participants from a population and then selects all members of that group.

  1. True

  2. False


Correct Option: A
Explanation:

Cluster sampling is a probability sampling technique where the researcher selects a group of participants from a population and then selects all members of that group.

Convenience sampling is a non-probability sampling technique where participants are selected based on their accessibility or convenience.

  1. True

  2. False


Correct Option: A
Explanation:

Convenience sampling is a non-probability sampling technique where participants are selected based on their accessibility or convenience.

Purposive sampling is a non-probability sampling technique where participants are selected based on their specific characteristics or expertise.

  1. True

  2. False


Correct Option: A
Explanation:

Purposive sampling is a non-probability sampling technique where participants are selected based on their specific characteristics or expertise.

Snowball sampling is a non-probability sampling technique where participants are recruited through referrals from other participants.

  1. True

  2. False


Correct Option: A
Explanation:

Snowball sampling is a non-probability sampling technique where participants are recruited through referrals from other participants.

Quota sampling is a non-probability sampling technique where participants are selected to match the characteristics of the population in terms of specific variables.

  1. True

  2. False


Correct Option: A
Explanation:

Quota sampling is a non-probability sampling technique where participants are selected to match the characteristics of the population in terms of specific variables.

Which sampling technique is most appropriate when the population is large and widely dispersed?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: D
Explanation:

Cluster sampling is most appropriate when the population is large and widely dispersed because it allows the researcher to select a representative sample without having to survey the entire population.

Which sampling technique is most appropriate when the population is small and homogeneous?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Convenience Sampling


Correct Option: A
Explanation:

Simple random sampling is most appropriate when the population is small and homogeneous because it ensures that each member of the population has an equal chance of being selected.

Which sampling technique is most appropriate when the researcher wants to ensure that specific subgroups are adequately represented in the sample?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Stratified Sampling

  4. Cluster Sampling


Correct Option: C
Explanation:

Stratified sampling is most appropriate when the researcher wants to ensure that specific subgroups are adequately represented in the sample because it allows the researcher to divide the population into subgroups and select participants from each subgroup.

Which sampling technique is most appropriate when the researcher wants to collect data from a specific group of individuals who share common characteristics?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Purposive Sampling

  4. Snowball Sampling


Correct Option: C
Explanation:

Purposive sampling is most appropriate when the researcher wants to collect data from a specific group of individuals who share common characteristics because it allows the researcher to select participants based on their specific characteristics or expertise.

Which sampling technique is most appropriate when the researcher wants to collect data from a large population quickly and economically?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Convenience Sampling

  4. Quota Sampling


Correct Option: C
Explanation:

Convenience sampling is most appropriate when the researcher wants to collect data from a large population quickly and economically because it allows the researcher to select participants based on their accessibility or convenience.

Which sampling technique is most appropriate when the researcher wants to collect data from a population that is difficult to access or identify?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Snowball Sampling

  4. Quota Sampling


Correct Option: C
Explanation:

Snowball sampling is most appropriate when the researcher wants to collect data from a population that is difficult to access or identify because it allows the researcher to recruit participants through referrals from other participants.

Which sampling technique is most appropriate when the researcher wants to collect data from a population that is spread over a large geographic area?

  1. Simple Random Sampling

  2. Systematic Sampling

  3. Cluster Sampling

  4. Quota Sampling


Correct Option: C
Explanation:

Cluster sampling is most appropriate when the researcher wants to collect data from a population that is spread over a large geographic area because it allows the researcher to select a representative sample without having to survey the entire population.
