When the results of a survey or poll are published, the sample
size and the margin of error are both given. For example: 1000
voters were surveyed and 39±2% of the voters agree with the
president. In this example N=1000 and the margin of error (MoE) is
2%.
This website lists several public opinion polls. Search the site
and find a poll where the sample size and margin of error are
given. Try to find a poll dealing with a topic in your profession
or one in which you are really interested
Determine the following information for the selected poll
results and include in your post:
- URL for the website
- Using your own words, state the topic of the poll in a full
sentence.
- State the sample size and margin of error.
- Interpret the results of your poll using your own words and
full sentences. Note: Depending on the question asked, your poll
may have more than one poll result – you only need to discuss one
result.
- Looking at the results with respect to the margin of error, is
there a significant difference among the various responses to the
question being asked?
- What role could sampling have played in determining these
results?
