Sampling Techniques: Stratified, Cluster, Systematic, and Convenience

What is the main characteristic of stratified sampling?

• Selecting random groups

• Selecting individuals from each group

• Selecting every nth individual

• Using readily available data

In a stratified sample of the United States, if 3 people are selected from each state, how many people are in the sample?

• 200

• 50

• 100

• 150

What is the key difference between stratified and cluster sampling?

• Stratified sampling uses readily available data, cluster sampling does not

• Stratified sampling selects individuals from each group, cluster sampling selects entire groups

• Stratified sampling selects groups, cluster sampling selects individuals

• Stratified sampling is random, cluster sampling is systematic

In cluster sampling, if you randomly select two states from the US, who is included in the sample?

• Every fifth individual in the two states

• Everyone in the two selected states

• Individuals from each state

• Only the first individual in each state

Which of the following is an example of cluster sampling?

• Selecting every 5th person from a list

• Surveying your neighbors

• Selecting 5 Taco Bell stores and including everyone in those stores

• Selecting 5 people from every Taco Bell

What is the first step in systematic sampling?

• Randomly selecting groups

• Using readily available data

• Selecting individuals from each group

• Ordering the data and assigning numbers

In systematic sampling, if you start with the 7th person and select every 5th person, who is the third person in your sample?

• 7th

• 12th

• 22nd

• 17th

Which sampling technique involves selecting every nth individual from an ordered list?

• Stratified sampling

• Convenience sampling

• Cluster sampling

• Systematic sampling

What is the main characteristic of convenience sampling?

• Using readily available data

• Selecting every nth individual

• Selecting individuals from each group

• Selecting random groups

Which of the following is an example of convenience sampling?

• Selecting every 5th person from a list

• Surveying your neighbors

• Randomly selecting 5 Taco Bell stores

• Selecting 5 people from every Taco Bell
