Surveying has been likened to taste-testing soup – a few spoonfuls tell what the whole pot tastes like. The key to the validity of any survey is randomness. Just as the soup must be stirred in order for the few spoonfuls to represent the whole pot, when sampling a population, the group https://www.isixsigma.com/tools-templates/sampling-data/margin-error-and-confidence-levels-made-simple/ must be stirred before respondents are selected. It is critical that respondents be chosen randomly so that the survey results can be generalized to the whole population. How well the sample represents the population is gauged by two important statistics – the survey's margin of error and confidence level. They tell us how well the spoonfuls represent the entire pot. For example, a survey may have a margin of error of plus or minus 3 percent at a 95 percent level of confidence. These terms simply mean that if the survey were conducted 100 times, the data would be within a certain number of percentage points above or below the percentage reported in 95 of the 100 surveys. In other words, Company X surveys customers and finds that 50 percent of the respondents say its customer service is "very good." The confidence level is cited as 95 percent plus or minus 3 percent. This information means that if the survey were conducted 100 times, the percentage who say service is "very good" will range between 47 and 53 percent most (95 percent) of the time.

accurate, assuming you counted the votes correctly. (By the way, there's a whole other topic in math that describes http://www.robertniles.com/stats/margin.shtml the errors people can make when they try to measure things like that. But, for now, let's assume you can count with 100% accuracy.) Here's the problem: Running elections costs http://www.huffingtonpost.com/2015/02/03/margin-of-error-debate_n_6565788.html a lot of money. It's simply not practical to conduct a public election every time you want to test a new product or ad campaign. So companies, campaigns and news organizations margin of ask a randomly selected small number of people instead. The idea is that you're surveying a sample of people who will accurately represent the beliefs or opinions of the entire population. But how many people do you need to ask to get a representative sample? The best way to figure this one is to think about it backwards. Let's say you picked margin of error a specific number of people in the United States at random. What then is the chance that the people you picked do not accurately represent the U.S. population as a whole? For example, what is the chance that the percentage of those people you picked who said their favorite color was blue does not match the percentage of people in the entire U.S. who like blue best? Of course, our little mental exercise here assumes you didn't do anything sneaky like phrase your question in a way to make people more or less likely to pick blue as their favorite color. Like, say, telling people "You know, the color blue has been linked to cancer. Now that I've told you that, what is your favorite color?" That's called a leading question, and it's a big no-no in surveying. Common sense will tell you (if you listen...) that the chance that your sample is off the mark will decrease as you add more people to your sample. In other words, the more people you ask, the more likely you are to get a rep

Natalie Jackson Senior Data Scientist, The Huffington Post Justin Lewis via Getty Images If you read polls in the news, you're probably familiar with the term "margin of error." What you may not know is that pollsters disagree fiercely about when it should be used. In an actual debate last week, sponsored by the do-it-yourself sampling firm Peanut Labs, polling experts got together to argue whether a margin of error should ever be reported for surveys conducted online -- which is how more and more surveys are conducted. Most industry standards and guidelines say that surveys drawn from nonrandom samples -- typically the case with online polling -- should not provide a margin of error when their results are generalized to the wider population. Yet, as debate moderator Annie Petit noted, many readers expect to see the margin of error, regardless of how the poll was done. So she threw out a provocative question: "Is it really so terrible to use a statistic that everyone understands so well?" At HuffPost Pollster, which regularly conducts online surveys with YouGov, we don't have a perfect answer to that. But we've decided it's time for even greater transpa
