percent of the participating Republicans in New Hampshire– down from 28 percent of respondents in September. Fiorina comes in second, with 16 percent support, up from 6 percent a month ago.

When taking the margin of error into consideration, the preferences of Republican voters are far from certain. But first, what is a margin of error (MOE)? It doesn’t measure most kinds of errors that plague many polls and surveys, like biased questions or selecting survey respondents in a way that’s not random. MOE does not measure a mistake, either. When a random sample of all Republicans is taken—a small group of people meant to be chosen randomly from all the possible likely Republican voters—there is always a possibility that the opinions of those in this sample don’t reflect those of the whole population. The MOE is a measurement of how confident we can be that such a survey of the opinions of a small number of people actually reflects the opinions of the whole population. Polls like these may have other major problems than simply sampling error. Quite possibly they haven’t accounted correctly for the demographics among the respondents to the polls. If those who respond are poorer, more likely to be white, less likely to be educated, or even less likely to vote, than those who actually vote, the survey will be biased. But assuming all of the iss

Rumsey You've probably heard or seen results like this: "This statistical survey had a margin of error of plus or minus 3 percentage points." What does this mean? Most surveys are based on information collected from a sample of individuals, not the entire population (as a census would be). A certain amount of error is bound to occur -- not in the margin of error sense of calculation error (although there may be some of that, too) but in the sense of sampling error, which is the error that occurs simply because the researchers aren't asking everyone. The margin of error is supposed to measure the maximum amount by which the sample results are expected to differ from those of the actual population. Because the results of most survey questions can be reported in terms of percentages, the margin of error most often appears as a percentage, as well. How do you interpret a margin of error? Suppose you know that 51% of people sampled say that they plan to vote for Ms. Calculation in the upcoming election. Now, projecting these results to the whole voting population, you would have to add and subtract the margin of error and give a range of possible results in order to have sufficient confidence that you're bridging the gap between your sample and the population. Supposing a margin of error of plus or minus 3 percentage points, you would be pretty confident that between 48% (= 51% - 3%) and 54% (= 51% + 3%
recount: Public should bear cost when difference is within machines' margin of error.December 1, 1998VICTORIA L. SCHADE just paid $9,750 to find out that she undeniably lost her seat in the Maryland House of Delegates to Democrat Mary Rosso in the 31st Legislative District last month. Ms. Schade did learn one fact for her money: She lost not by 18 votes, as originally believed, but by 6. The recount did not change the outcome, but it was instructive nonetheless.We like to think that voting machines make election tallies less subject to error, but the recount demonstrates that machines, like humans, are capable of mistakes.ARTICLES BY DATESPORTSRavens again show how slim margin of error is, an actual running game and more from Sunday's loss to the Chicago BearsBy Matt Vensel and The Baltimore Sun | November 18, 2013When the Ravens resumed control of the football at their 16-yard line with just under five minutes left to play Sunday, it felt as if the Chicago Bears' end zone was 184 yards away, not 84. Their offense had struggled to get traction, both literally and figuratively, in the second half and now trailed by a field goal. Facing long odds of winning, the Ravens needed to put together one efficient drive. And they would. After two incompletions to start the drive, their win probability was at 22 percent, according to Advanced NFL Stats.Advertisement BUSINESSWork clothes send signalsBy Hanah Cho and Tyeesha Dixon and Hanah Cho and Tyeesha Dixon,Sun reporters | October 25, 2006You dress up for job interviews and meetings with clients. That's a given. But making a good first impression isn't the only way your fashion style comes into play. Colleagues size up your outfits to decide whether you're stodgy or fun, among other things. That's according to a recent survey by TheLadders.com, a job site for executives. More than 70 percent of respondents said that employees dressed in suits are seen as more senior-level, while 60 percent believe those workers are taken more seriously.BUSINESSPutting your vote where your money isBy EILEEN AMBROSE and EILEEN AMBROSE,eileen.ambrose@baltsun.com | October 4, 2008Each voter has his or her own reason for selecting a candidate for president.
