For example, suppose

we wanted to know the percentage of adults that exercise daily. We could devise a sample design to ensure that our sample estimate will not differ from the true population value by more than, say, 5 percent (the margin of error) 90 percent of the time (the confidence level). How to Compute the Margin of Error The margin of error can be

defined by either of the following equations. Margin of error = Critical value x Standard deviation of the statistic Margin of error = Critical value x Standard error of the statistic If you know the standard deviation of the statistic, use the first equation to compute the margin of error. Otherwise, use the second equation. Previously, we described how to compute the standard deviation and standard error. How to Find the Critical Value The critical value is a factor used to compute the margin of error. This section describes how to find the critical value, when the sampling distribution of the statistic is normal or nearly normal. The central limit theorem states that the sampling distribution of a statistic will be nearly normal, if the sample size is large enough. As a rough guide, many statisticians say that a sample size of 30 is large enough when the population distribution is bell-shaped. But if the original population is badly skewed, has multiple peaks, and/or has outliers, researchers like the sample size to be even larger. When the sampling distribution is nearly normal, the critical

engineering, see Tolerance (engineering). For the eponymous movie, see Margin for error (film). The top portion charts probability density against actual percentage, showing the relative probability that the actual percentage sampling error is realised, based on the sampled percentage. In the bottom portion, each

line segment shows the 95% confidence interval of a sampling (with the margin of error on the left, and unbiased confidence interval error bars excel samples on the right). Note the greater the unbiased samples, the smaller the margin of error. The margin of error is a statistic expressing the amount of random sampling error in a http://stattrek.com/estimation/margin-of-error.aspx survey's results. It asserts a likelihood (not a certainty) that the result from a sample is close to the number one would get if the whole population had been queried. The likelihood of a result being "within the margin of error" is itself a probability, commonly 95%, though other values are sometimes used. The larger the margin of error, the less confidence one should have https://en.wikipedia.org/wiki/Margin_of_error that the poll's reported results are close to the true figures; that is, the figures for the whole population. Margin of error applies whenever a population is incompletely sampled. Margin of error is often used in non-survey contexts to indicate observational error in reporting measured quantities. In astronomy, for example, the convention is to report the margin of error as, for example, 4.2421(16) light-years (the distance to Proxima Centauri), with the number in parentheses indicating the expected range of values in the matching digits preceding; in this case, 4.2421(16) is equivalent to 4.2421 ± 0.0016.[1] The latter notation, with the "±", is more commonly seen in most other science and engineering fields.

It helps to find authoritative sources and focus on them to help resolve such issues. A pamphlet published by the American Statistical Association (attributed to Fritz Scheuren and "thoroughly updated circa 1997") defines the margin of error as a 95% confidence interval (p. 64, at right). In light of this, it is surprising that the Wikipedia article on margin of error uses a different definition, even though it references this pamphlet! Wikipedia writes, The margin of error is usually defined as the "radius" (or half the width) of a confidence interval for a particular statistic from a survey. ... When a single, global margin of error is reported for a survey, it refers to the maximum margin of error for all reporte

information about a sample. One very vivid application is currently in the news: polls attempt to determine the way a population will vote by examining the voting patterns within a sample. The idea of generalizing from a sample to a population is not hard to grasp in a loose and informal way, since we do this all the time. After a few vivits to a store, for example, we notice that the produce is not fresh. So we assume that the store generally has bad produce. This is a generalization from a sample (the vegetables we have examined) to a population (all the vegetables the store sells). But there are many ways to go wrong or to misunderstand the meaning of the data obtained from a sample. How do statisticians conceive of the process of drawing a conclusion about a population from a sample? How do they describe the information that is earned from a sample and quantify how informative it is? How much data do we need in order to reach a conclusion that is secure enough to print in a newpaper? Or on which to base medical decisions? These are the questions that we will address this week. The simplest example arises when one uses a sample to infer a population proportion. We can give a fairly complete account of the mathematical ideas that are used in this situation, based on the binomial distribution. My aim is to enable you to understand the internal mathematical "clockwork" of how the statistical theory works. Assignment: Read: Chapter 8, sections 1, 2 and 3. For the time being, do not worry about pasages that contain references to the "normal distribution" of the "Central Limit Theorem" . (Last sentence on page 328, last paragraph on p. 330, first paragraph on p. 332.) Also, do not worry for the time being about the examples in section 3.2. Review questions: pages 335 and 351. Problems: p. 336: 1--8, 11, 12, 13, 14. p. 351: 1--12, 13, 16, 21, 22. In-class: p. 337: 20. EXTRA CREDIT: Find an article in the New York Times that describes a poll. The New York Times provides readers with a very careful explanantion of margin of error and level of confidence; find their explanation either in an issue of the paper or on the paper's web site, and report on it. Compare with the information provided by other papers. Vocabulary: Parameters and statistics: population mean: the average value of a variable, where the reference class is a population of interest. E.g. the average high of all persons owning a Louisiana driver's license. This is a parameter. sample mean: the average value of a variable, where the reference class is a sample from the population. This is a statistic. It is also a variable that has as its refernce class all possible sampl

There are many reasons why Confidence Error happen, including having malware, spyware, or programs not installing properly. You can have all kinds of system conflicts, registry errors, and Active X errors. Reimage specializes in Windows repair. It scans and diagnoses, then repairs, your damaged PC with technology that not only fixes your Windows Operating System, but also reverses the damage already done with a full database of replacement files.

A FREE Scan (approx. 5 minutes) into your PC's Windows Operating System detects problems divided into 3 categories - Hardware, Security and Stability. At the end of the scan, you can review your PC's Hardware, Security and Stability in comparison with a worldwide average. You can review a summary of the problems detected during your scan. Will Reimage fix my Confidence Error problem? There's no way to tell without running the program. The state of people's computers varies wildly, depending on the different specs and software they're running, so even if reimage could fix Confidence Error on one machine doesn't necessarily mean it will fix it on all machines. Thankfully it only takes minutes to run a scan and see what issues Reimage can detect and fix.

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.

A **stop error screen** or **bug check screen**, commonly called a **blue screen of death** (also known as a **BSoD, bluescreen**), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".

One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.

**Computer hanging** or **freezing** occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.

Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.

Reimage repairs and replaces all critical Windows system files needed to run and restart correctly, without harming your user data. Reimage also restores compromised system settings and registry values to their default Microsoft settings. You may always return your system to its pre-repair condition.

Reimage patented technology, is the only PC Repair program of its kind that actually reverses the damage done to your operating system. The online database is comprised of over 25,000,000 updated essential components that will replace any damaged or missing file on a Windows operating system with a healthy version of the file so that your PC's performance, stability & security will be restored and even improve. The repair will deactivate then quarantine all Malware found then remove virus damage. All System Files, DLLs, and Registry Keys that have been corrupted or damaged will be replaced with new healthy files from our continuously updated online database.
