Quiz on Sampling and its Types

What is a sample in research?

• A random selection of data

• A method of data analysis

• A subset of the population

• A complete examination of the population

What is the main purpose of using sampling in research?

• To ensure complete accuracy

• To avoid any errors

• To save time and resources

• To gather data from every individual

Which of the following is a characteristic of a sampling unit?

• It must be selected randomly

• It must be a single member of the sample

• It must be a large group

• It can be interchangeable

What type of sampling allows each member of the population an equal chance of being selected?

• Non-probability sampling

• Convenience sampling

• Probability sampling

• Judgment sampling

In systematic sampling, what is the first step after arranging the population?

• Select a random number

• Choose the sample size

• Calculate the sampling frame

• Identify the strata

What is the difference between sampling error and non-sampling error?

• Sampling error occurs due to incorrect data entry

• Non-sampling error is due to a non-representative sample

• Sampling error is due to a non-representative sample

• Non-sampling error occurs only in probability sampling

Which sampling method is used when the desired sample characteristic is rare?

• Simple random sampling

• Cluster sampling

• Snowball sampling

• Stratified sampling

What is the main disadvantage of convenience sampling?

• It is time-consuming

• It is expensive

• It may not be representative

• It requires a large sample size

What does stratified random sampling involve?

• Selecting samples from a single group

• Selecting samples randomly from the entire population

• Using convenience sampling

• Dividing the population into strata

Which of the following is true about cluster sampling?

• It is the same as stratified sampling

• It divides the population into homogeneous groups

• It is useful for widely dispersed populations

• It requires a complete sampling frame
