Understanding the margin of error in surveys

Throughout the year, and especially before any election, we can find a plethora of survey results showing
respondents’ opinions on some topic. These surveys will report a margin of error (typically +/- 3%).
Using your new knowledge of margins of error, describe an example where knowing the margins of error may
affect your interpretation of the results? Discuss how this might happen (or how it has happened, if it’s a reallife example). How might the situation be improved?
