actual percentage is realised, based on the sampled percentage. In the bottom margin of error calculator portion, each line segment shows the 95% confidence interval of a sampling (with the margin of error on the margin of error definition left, and unbiased 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 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 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,

Raul654 writes "Nature magazine recently conducted a head-to-head competition between Wikipedia and Britannica, having experts compare 42 science-related articles. The result was that Wikipedia had about 4 errors per article, while Britannica had about 3. However, a pair of endevouring Wikipedians dug a little deeper and discovered margin of error that the Wikipedia articles in the sample were, on average, 2.6 times longer than Britannica's - meaning Wikipedia has an error rate far less than Britannica's." Interesting, considering some past claims.

This is divided into different horizontal portions named bands. When the report is joined with the data generating the print, this section is printed many times according to their functions (and according to the rules that the report author has set up). For instance, the page header is repeated at the beginning of every page, while the detail band is repeated for every single read record. What is a Band The type page is divided into nine predefined bands to which new groups are added. In addition, Jaspersoft Studio manages a heading band (group header) and a recapitulation band (group footer) for every group. A band is always wide as the page width (right and left margins excluded). However, its height, even if it is established during the design phase, can vary during the print creation according to the contained elements; it can "lengthen" toward the bottom of a page in an arbitrary way. This typically occurs when bands contain subreports or text fields that have to adapt to the content vertically. Generally, the height specified by the user should be considered "the minimal height" of the band. Not all bands can be stretched dynamically according to the content, in particular the column footer, page footer and last page footer bands. The sum of all band heights (except for the background) has to always be less than or equal to the page height minus the top and bottom margins. Band Types Following there is a brief descriptions of the available bands. Title The title band is the first visible band. It is created only once and can be printed on a separate page. Regarding the allowed dimensions, it is not possible during design time to exceed the report page height (top and bottom margins are included). If the title is printed on a separate page, this band height is not included in the calculation of the total sum of all band heights, which has to be less than or equal to the page height, as was mentioned previously. Page Header The page header band allows you to define a page header. The height specified during the design phase usually does not change during the creation process (except for the insertion of vertically resizable components, such as a text fi
