**This was the original question and I need to reply to my classmate in a minimum 100 words without references:
This is a classmate’s response to the above discussion question:
“One statistical method we can apply to the census data is to determine the confidence interval and margin of error of the sample compared to the total population. I believe this will be an important piece of the analysis because we would want to establish the level of certainty/uncertainty in the data collected. The data can also be split into different categories based on the answers to the questions (demographics, race, age, region, etc). We can use t-testing to compare multiple samples and find the p-value, which will provide information on how statistically relevant the data actually is. Establishing relevance and certainty in the data will give us a better understanding of how well the sample represents the population, therefore allowing us to making inferences about the population as a whole. The accuracy of the data would be a known limitation of the data because most of the data is self-reported and as humans, we are always apt to make some sort of errors. The manually collected data has an even higher probability of inaccuracies because it passes through two different hands.”
