Find a news article that mentions an estimate of a population proportion of population mean (remember, the article will not likely use those exact terms — more likely it will say things like “a survey shows that the percentage of people that…” or “researches found that, on average…”). Find the study that it was based on and find out what the actual confidence interval is for that estimate (remember, this can be calculated if the margin of error is given).
If you don’t know where to start, articles that mention polls, surveys, or “recent studies” usually reference this kind of research. In the article, look for statements such as, “in a recent poll by the Pew Research Center…;” from here you can search for the original study information from Pew Research, which will have the margin of error or confidence interval information.
Once you have found this information share in this discussion the information from the study (what the results and interval/margin of error were) and give a link to the place where you found that information.
Pro tip: I would look for something regarding political opinions; likely voting, policy sentiments, voter priorities, etc. are all things that often times have pretty good information available and are frequently found on news sites.
