Bias tape or bias binding is a narrow strip of fabric, cut on the bias textile bias UK cross grain . The strip s fibers, being at 45 degrees to the length of the strip, makes it stretchier as well as more fluid and more drapeable compared to a strip that is cut on the grain. Many strips can be pieced together into a long tape. The tape s width varies from about 1 2 to about 3 depending on applications. Bias tape is used in making Piping sewing piping , Bound seam binding seams , finishing raw edges, etc. It is often used on the edges of quilts, placemats, and bibs, around armhole and neckline edges instead of a facing, and as a simple strap or tie for casual bags or clothing.

In statistics , the term bias refers to several different concepts Selection bias , where individuals or groups are more likely to take part in a research project than others, resulting in biased sample s. This can also be termed Berksonian bias . ref Rothman, K.J. et al. 2008 Modern epidemiology. Lippincott Williams & Wilkins pp.134 137. ref Spectrum bias arises from evaluating diagnostic tests on biased patient samples, leading to an overestimate of the sensitivity and specificity of the test. The bias of an estimator is the difference between an estimator s expectation and the true value of the parameter being estimated. Omitted variable bias is the bias that appears in estimates of parameters in a regression analysis when the assumed specification is incorrect, in that it omits an independent variable that should be in the model. In statistical hypothesis testing , a test is said to be unbiased when the probability of rejecting the null hypothesis exceeds the significance level when the alternative is true and is less than or equal to the significance level when the null hypothesis is true. Systematic bias or systemic bias are external influences that may affect the accuracy of statistical measurements. Detection bias is where a phenomenon is more likely to be observed and or reported for a particular set of study subjects. For instance, the syndemic involving obesity and Diabetes mellitus diabetes may mean doctors are more likely to look for diabetes in obese patients than in less overweight patients, leading to an inflation in diabetes among obese patients because of skewed detection efforts. Funding bias may lead to selection of outcomes, test samples, or test procedures that favor a study s financial sponsor. Reporting bias involves a skew in the availability of data ... in research.

Image Bias textile .gif right thumb 200px Bias or cross grain of cloth. The bias US or cross grain UK direction of a piece of weave woven Textile fabric , usually referred to simply as the bias or the cross grain , is at 45 degrees to its Warp weaving warp and weft threads. Every piece of woven fabric has two biases, perpendicular to each other. Non woven fabrics such as felt or interfacing do not have a bias. Woven fabric is more elastic as well as more fluid in the bias direction, compared to the on grain direction. This property facilitates clothing garments and garment details that require extra elasticity, drapability or flexibility, such as bias cut skirts and dresses, necktie s, piping trim sewing trims and decorations, bound seams, etc. The bias cut is a technique used by designers for cutting clothing to utilize the greater stretch in the bias or diagonal direction of the fabric, thereby causing it to accentuate body lines and curves and drape softly. For example, a full skirted dress cut on the bias will hang more gracefully or a narrow dress will cling to the figure. Bias cut garments were an important feature of the designs of Madeleine Vionnet in 1920s and 1930s and bias cut styles are revived periodically. In the Middle Ages, before the development of knitting, hose were cut on the bias in order to make them fit better. The old spelling was byesse. A garment made of woven fabric is said to be cut on the bias when the fabric s warp and weft threads are at 45 degrees to its major seam lines. Note The term cross grain in the US refers to the direction perpendicular to the length of grain selvage edges , not the diagonal.

The inductive bias of a learning algorithm is the set of assumptions that the learner uses to predict outputs given inputs that it has not encountered Mitchell, 1980 . In machine learning , one aims to construct algorithms that are able to learn to predict a certain target output.

Bias knitting is a method by which the grain of a knitted fabric is skewed from the vertical, by decreasing on one side and increasing on the other. The term bias derives from sewing , where bias refers to the diagonal between the weft and warp threads, where the Elasticity fabrics elasticity of woven s is greatest. A classic use of bias knitting is in making a saw toothed knitted hemline for a garment , with a central double decrease knitting decrease flanked by single increase knitting increases on either side.

Egocentric bias occurs when people claim more responsibility for themselves for the results of a joint action than an outside observer would credit them. Besides simply claiming credit for positive outcomes, which might simply be self serving bias , people exhibiting egocentric bias also cite themselves as overly responsible for negative outcomes of group behavior as well however this last attribute would seem to be lacking in megalomania . This may be because our own actions are more available to us than the actions of others. See availability heuristic .

Response bias is a type of cognitive bias which can affect the results of a statistical survey if respondents answer questions in the way they think the questioner wants them to answer rather than according to their true belief s. This may occur if the questioner is obviously angling for a particular answer as in push polling or if the respondent wishes to please the questioner by answering what appears to be the morally right answer. An example of the latter might be if a woman surveys a man on his attitudes to domestic violence , or someone who obviously cares about the natural environment environment asks people how much they value a wilderness area . This occurs most often in the wording of the question . Response bias is present when a question contains a leading opinion. For example, saying Given that at the age of 18 people are old enough to fight and die for your country, don t you think they should be able to drink alcohol as well? yields a response bias. It is better to say Do you think 18 year olds should be able to drink alcohol? It also occurs in situations of voluntary response, such as phone in polls, where the people who care enough to call are not necessarily a statistically representative sample of the actual population. Non response bias is not the opposite of response bias and is not a type of cognitive bias it occurs in a statistical survey if those who respond to the survey differ in the outcome variable for example, evaluation of the need for financial aid from those who do not respond. Often, the differences, which may include race, gender or socioeconomic ....

For other uses of Malmquist Malmquist disambiguation Unreferenced stub auto yes date December 2009 The Malmquist bias , named after the Swedish astronomer Gunnar Malmquist 1893 1982 , is a selection effect in observational astronomy . Specifically, if a sample of objects galaxy galaxies , quasar s, star s, etc. is Jansky flux limited, then the observer will see an increase in average luminosity with distance. This is, of course, because the less luminous sources at large distances will not be detected. The solution is then to use a sample that is not magnitude limited for example, one that is volume limited. See also Great Attractor Sampling bias References Martin A. Hendry, John F. L.

In digital photography , a bias frame is an image obtained from an opto electronic image sensor , with no actual exposure time. The image so obtained only contains noise due to the electronics that elaborate the sensor data, and not noise from charge accumulation e.g. from dark current within the sensor itself. A bias frame is complementary to a dark frame , which has a charge integration time but in darkness. Since a dark frame contains noise including a fixed pattern noise component, some of which corresponds to the bias frame, and some of which is due to dark current and is proportional to the exposure time, it is possible to obtain an image representing only the dark current component by subtracting a bias frame from a dark frame. The resulting image allows obtaining an artificial dark frame when multiplied by a factor depending on exposure time and then added back to the bias frame. Although this technique is less accurate than shooting a dark frame for each specific exposure duration, it has the advantage of drastically reducing the time needed to obtain dark frame data for dark frame subtraction .

A forecast bias occurs when there are consistent differences between actual outcomes and previously generated forecasts of those quantities that is, forecasts may have a general tendency to be too high or too low. A normal property of a good forecast is that it in not biased. ref APICS Dictionary 12th Edition. Available for download at http www.apics.org Resources APICSDictionary.htm ref . As a quantitative measure, the forecast bias can be specified as a probabilistic or statistical property of the forecast error . A typical measure of Bias statistics bias of forecasting procedure is the arithmetic mean or expected value of the forecast errors, but other measures of bias are possible. For example, a median unbiased forecast would be one were half of the forecasts are too low and half too high see Bias of an estimator . In contexts where forecasts are being produced on a repetitive basis, the performance of the forecasting system may be monitored using a tracking signal , which provides an automatically maintained summary of the forecasts produced up to any given time. This can be used to monitor for deteriorating performance of the system.

No footnotes date March 2011 FUTON bias short for Full Text On the Net bias refers to the bias in academic research , when researchers are more likely to search and read what is available online , and ignore relevant studies that are available offline in printed format only. As a result, articles that are available as full text on the Internet have more visibility and impact, as they are more likely to be accessed, read and quoted. FUTON bias is a result of several factors. Very few libraries in general have a full range of journals available, and if the article is available, it may be only in print or microform . Also, online research is becoming easier and less time consuming than offline research. FUTON bias tends to result in older sources getting less visibility, as they are less likely to have been digitized . Similarly, sources published in less developed countries are similarly adversely affected, as those countries tend to have less resources that can be spared for digitalization see digital divide . No abstract available bias NAA bias is similar to FUTON bias it occurs when an article has no abstract summary abstract available online.
