Module 2. Quiz No.2-Sampling Techniques in Qualitative Research

What is the purpose of sampling in research?

• Sampling helps researchers generalize findings, reduce costs, and save time.

• Sampling is used to limit the scope of research, increase variability, and introduce bias.

• Sampling helps researchers manipulate data, increase costs, and waste time.

• Sampling is primarily used to ensure accurate results, increase resources, and prolong the research process.

Answer explanation

Sampling helps researchers generalize findings, reduce costs, and save time, making it the correct choice.

What are the different types of sampling techniques?

• judgmental sampling

• quota sampling

• randomized sampling

• simple random sampling, systematic sampling, stratified sampling, cluster sampling, convenience sampling

Answer explanation

The different types of sampling techniques include simple random sampling, systematic sampling, stratified sampling, cluster sampling, and convenience sampling.

How does sampling bias affect qualitative research?

• Sampling bias only affects quantitative research, not qualitative research.

• Sampling bias enhances the validity of qualitative research findings.

• Sampling bias has no impact on the data collected in qualitative research.

• Sampling bias affects qualitative research by distorting the validity and reliability of the data collected.

Answer explanation

Sampling bias affects qualitative research by distorting the validity and reliability of the data collected.

What are the common sampling methods used in qualitative research?

• Random sampling, cluster sampling, stratified sampling, quota sampling

• Purposive sampling, snowball sampling, convenience sampling, theoretical sampling

• Judgmental sampling, accidental sampling, systematic sampling, cluster sampling

• Volunteer sampling, quota sampling, accidental sampling, systematic sampling

Answer explanation

The common sampling methods used in qualitative research are purposive sampling, snowball sampling, convenience sampling, and theoretical sampling.

Explain the various sampling strategies in qualitative research.

• Purposive sampling

• Cluster sampling

• Random sampling

• Purposeful sampling, snowball sampling, theoretical sampling, convenience sampling, and quota sampling.

Answer explanation

The correct answer includes purposeful sampling, snowball sampling, theoretical sampling, convenience sampling, and quota sampling as various sampling strategies in qualitative research.

Describe the sampling procedures followed in qualitative research.

• Random sampling

• Sampling procedures in qualitative research include purposeful sampling, snowball sampling, theoretical sampling, and convenience sampling.

• Cluster sampling

• Stratified sampling

Answer explanation

Sampling procedures in qualitative research include purposeful sampling, snowball sampling, theoretical sampling, and convenience sampling.

Which non-probability sampling technique is characterized by selecting participants based on their availability? (A) Convenience (B) Criterion (C) Critical case (D) Snowball sampling

• Quota

• Purposive

• A

• Random

Answer explanation

Convenience sampling involves selecting participants based on their availability, making it the correct choice in this scenario.

Which non-probability sampling technique involves selecting participants based on specific criteria or characteristics? (A) Convenience (B) Criterion (C) Critical case (D) Snowball sampling

• Criterion

• Quota

• Random

• Cluster

Answer explanation

Criterion sampling involves selecting participants based on specific criteria or characteristics, making it the correct choice in this scenario.

Which non-probability sampling technique focuses on extreme or unique cases? (A) Convenience (B) Criterion (C) Critical case (D) Snowball sampling

• A. Random

• B. Quota

• C

• D. Cluster

Answer explanation

The correct answer is (C) Critical case. Critical case sampling focuses on extreme or unique cases to provide in-depth insights into specific situations.

Which non-probability sampling technique relies on existing participants to recruit new participants? (A) Convenience (B) Criterion (C) Critical case (D) Snowball sampling

• Snowball sampling

• Stratified sampling

• Cluster sampling

• Random sampling

Answer explanation

Snowball sampling relies on existing participants to recruit new participants, making it a non-probability sampling technique.
