Pollster

(Phase 2)

At this point you should be done with the canvasser stage and, hence, have all your data collected. So it's time to don your statistician's cap and start crunching numbers.

The first thing you will want to do is figure out the percentages for each question you asked. Hopefully now you will appreciate the fact that you polled 100 people. If not, here's why you should be…

If 32 people responded "yes" one of your questions, then you can make the observation that 32 out of 100 people said yes. A percentage is simply a comparison to 100, so this would be 32%. Awesome, huh? Go through and in this way find all the percentages for the polling you did.

But there is a bit more to the story. Remember, you didn't ask absolutely everybody your poll questions, and even though your random sample will make your data quite representative of the population, you still have to admit that there might be some sort of error in the conclusions you draw. To investigate "margin of error," visit these sites:

- A nice explanation of "margin for error."
- Use the table on this site to find your margin for error. Be sure to include this information in your article.
