Sampling Bias Quiz

How can convenience sampling lead to bias?

• It ensures a diverse sample.

• It only includes easily accessible subjects.

• It uses random selection.

• It eliminates all biases.

What is a potential issue with voluntary response sampling?

• It guarantees a representative sample.

• It often includes only those with strong opinions.

• It uses a systematic approach.

• It avoids all forms of bias.

How does random sampling help to avoid bias?

• It selects participants based on convenience.

• It includes only volunteers.

• It gives each member of the population an equal chance of being selected.

• It focuses on a specific subgroup.

What does poor sampling lead to in statistical studies?

• Accurate and representative sample data

• Biased and unrepresented sample data

• Increased sample size

• Reduced variability

What is a characteristic of a statistical study with bias?

• It consistently provides accurate results

• It consistently underestimates or overestimates the value being measured

• It uses a large sample size

• It is always random

What is a convenience sample?

• A sample where individuals are chosen randomly.

• A sample where individuals are chosen because they are easy to reach.

• A sample that represents the entire population accurately.

• A sample that includes only individuals who are difficult to reach.

What is a potential drawback of using a convenience sample?

• It always represents the population accurately.

• It may result in a sample that does not adequately represent the population.

• It is the most expensive sampling method.

• It requires a lot of time to conduct.

Why might a voluntary response sample not adequately represent the population?

• Because it includes everyone in the population

• Because participants may have specific characteristics, attitudes, or experiences that differ from those who do not participate

• Because it is always a large sample

• Because it is randomly selected

What is the second step in describing bias?

• Identify the source

• Describe the misrepresentation

• Describe the direction of the bias

• Collect more data

What is the third step in describing bias?

• Describe the direction of the bias

• Identify the source

• Describe the misrepresentation

• Validate the data
