Sampling Techniques Quiz

What is the primary purpose of sampling in business research?

• To eliminate bias in research

• To ensure every case is included

• To reduce the amount of data collected

• To collect data from the entire population

Which of the following is a characteristic of probability sampling?

• Selection is based on judgment

• It requires a smaller sample size

• Each case has a known chance of selection

• It is always more accurate than non-probability sampling

What is the term for the complete set of cases from which a sample is drawn?

• Sampling technique

• Sample size

• Population

• Sample frame

Which sampling technique involves selecting every nth case from a list?

• Stratified sampling

• Cluster sampling

• Systematic sampling

• Simple random sampling

What is a key disadvantage of using existing databases for sampling frames?

• They may contain incomplete information

• They are easy to access

• They are always up to date

• They are always accurate

In probability sampling, what does a larger sample size generally lead to?

• Increased bias

• Lower confidence in results

• More accurate generalizations

• Higher margin of error

What is the first step in the probability sampling process?

• Identify a suitable sampling frame

• Choose the sampling technique

• Select the sample size

• Check sample representativeness

Which of the following is NOT a type of probability sampling?

• Quota sampling

• Stratified random sampling

• Simple random sampling

• Cluster sampling

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

• Statistical inference

• Subjective judgment

• Random selection

• Population representation

What is the purpose of stratified random sampling?

• To simplify the sampling process

• To ensure representation from specific subgroups

• To eliminate the need for a sampling frame

• To select cases randomly from the entire population
