Quiz on Non-Probability Sampling Techniques

What is the main characteristic of non-probability sampling techniques?

• Participants are selected based on their performance.

• The probability of selection is known.

• Participants are selected randomly.

• Selection is not based on randomness.

Which non-probability sampling technique involves selecting participants based on their availability?

• Convenience Sampling

• Snowball Sampling

• Purposive Sampling

• Quota Sampling

In which sampling method does the researcher deliberately select participants based on specific characteristics?

• Snowball Sampling

• Purposive Sampling

• Convenience Sampling

• Volunteer Sampling

What is a potential drawback of snowball sampling?

• It can introduce bias.

• It is too expensive.

• It is time-consuming.

• It guarantees a representative sample.

What does quota sampling ensure?

• The sample is large enough.

• Participants are selected randomly.

• Certain subgroups are represented.

• All participants are volunteers.

Which method allows participants to self-select for a study?

• Convenience Sampling

• Quota Sampling

• Volunteer Sampling

• Purposive Sampling

What is a limitation of non-probability sampling techniques?

• They require a large sample size.

• They are always representative.

• They can calculate statistical measures easily.

• They may not be generalizable.

When are non-probability sampling techniques often used?

• When probability sampling is not feasible.

• When researchers want random samples.

• When researchers have unlimited resources.

• When the target population is large.
