Sampling Methods

What is the specific group of individuals that you will collect data from?

• Quota

• Cluster

• Sample

• Population

Which sampling method involves random selection, allowing you to make strong statistical inferences about the whole group?

• Simple random sampling

• Snowball sampling

• Purposive sampling

• Convenience sampling

In which type of sampling method does every member of the population have a chance of being selected?

• Cluster sampling

• Stratified sampling

• Systematic sampling

• Probability sampling

What type of sampling involves dividing the population into subpopulations that may differ in important ways?

• Systematic sampling

• Quota sampling

• Cluster sampling

• Stratified sampling

Which sampling method involves non-random selection based on convenience or other criteria?

• Systematic sampling

• Cluster sampling

• Non-probability sampling

• Simple random sampling

What is the main purpose of snowball sampling?

• To ensure that every subgroup is properly represented in the sample

• To select a sample that is most useful to the purposes of the research

• To recruit participants via other participants

• To divide the population into subgroups

In which type of sampling method does the researcher use their expertise to select a sample that is most useful to the purposes of the research?

• Convenience sampling

• Purposive sampling

• Snowball sampling

• Quota sampling

What is the main characteristic of quota sampling?

• It relies on non-random selection of a predetermined number or proportion of units

• It allows you to easily collect data

• It involves random selection of a predetermined number or proportion of units

• It involves dividing the population into subgroups

What is the purpose of stratified sampling?

• To select a sample that is most useful to the purposes of the research

• To divide the population into subgroups

• To ensure that every subgroup is properly represented in the sample

• To recruit participants via other participants

What is the main characteristic of systematic sampling?

• It involves random selection based on convenience or other criteria

• It involves dividing the population into subgroups

• It is similar to simple random sampling, but it is usually slightly easier to conduct

• It allows you to make strong statistical inferences about the whole group
