What is the term for the group of individuals, items, or units under investigation in research?

• Sample

• Population

• Universe

• Census

A subset of the population selected for study is called:

• Population

• Sampling Unit

• Sample

• Data Set

What is the process of selecting a sample from a population?

• Data collection

• Research methodology

• Sampling

• Data analysis

One of the advantages of sampling is:

• It covers the entire population

• It requires more time and effort

• It reduces cost and increases speed

• It always eliminates bias

A major disadvantage of sampling is:

• It is always error-free

• It requires specialized knowledge

• It is more expensive than studying the whole population

• It never provides reliable data

Which type of sampling gives each member of the population an equal chance of selection?

• Non-probability sampling

• Convenience sampling

• Probability sampling

• Purposive sampling

Which type of probability sampling selects individuals randomly without bias?

• Systematic sampling

• Stratified sampling

• Cluster sampling

• Simple random sampling

In systematic sampling, individuals are selected:

• Based on researcher's judgment

• After every fixed interval

• Using quota requirements

• Based on referrals

Stratified sampling divides the population into:

• Equal sample sizes

• Homogeneous groups (strata)

• Randomly assigned clusters

• Large primary units

Cluster sampling is also known as:

• Quota sampling

• Area sampling

• Snowball sampling

• Systematic sampling
