Final answer:
The potential differences between Census data and the actual population in Andrew's research may stem from sampling methods, response bias, and temporal changes in demographics.
Step-by-step explanation:
Certainly! Here is the information divided into bullet points:
The census data may differ from the actual population due to the use of sampling methods.
Andrew's research may involve a subset of the population rather than the entire population.
Differences may arise from individuals choosing not to participate or providing inaccurate information.
This bias could affect the accuracy of the census data compared to the true population characteristics.
Changes in the population between the time of the census and Andrew's research may lead to discrepancies.
Demographic shifts, migrations, or other temporal variations could impact the alignment of the two datasets.
