How can bias affect research conclusions?

• Bias can lead to incorrect conclusions by favoring certain outcomes or perspectives over others.

• Bias ensures that all perspectives are equally represented in research.

• Bias has no effect on the validity of research conclusions.

• Bias only affects qualitative research, not quantitative research.

How can convenience samples lead to bias?

• They are always representative of the population.

• They may not include all segments of the population.

• They are more cost-effective than random samples.

• They require less time to collect data.

What is the importance of sample size in research?

• A larger sample size generally leads to more reliable and valid results, reducing the margin of error.

• A smaller sample size is always sufficient for accurate results.

• Sample size has no impact on the validity of research findings.

• Increasing sample size increases the cost but not the reliability of results.

What is an unbiased sample?

• An unbiased sample is one that accurately represents the population, giving all individuals an equal chance of being selected.

• An unbiased sample is one that includes only the most vocal members of a population.

• An unbiased sample is one that is selected randomly without any consideration of the population's characteristics.

• An unbiased sample is one that is chosen based on convenience and accessibility.
