Bias tape or bias binding is a narrow strip of fabric, typically plain weave, cut on the bias. As the weave of fabric is at a 45-degree angle, the resulting fabric strip is stretchier than a strip cut on the grain. The strip also has a better drape, and conforms to curves better than fabric cut on the grain. [1]
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.
The anchoring bias, or focalism, is the tendency to rely too heavily—to "anchor"—on one trait or piece of information when making decisions (usually the first piece of information acquired on that subject). [11] [12] Anchoring bias includes or involves the following:
In statistics, the bias of an estimator (or bias function) is the difference between this estimator's expected value and the true value of the parameter being estimated. An estimator or decision rule with zero bias is called unbiased. In statistics, "bias" is an objective property of an estimator.
Here's why every fashion plate you know owns them
The bias is indicated by values on the vertical axis different from unity; that is, if there were no bias, the ratio of the estimated to known standard deviation would be unity. Clearly, for modest sample sizes there can be significant bias (a factor of two, or more).
The difference between bias noise and the noise of virgin tape is an indicator of tape uniformity. Another important but rarely quantified type of noise is modulation noise, which appears only in the presence of a recorded signal, and which cannot be reduced by Dolby or dbx noise reduction systems.
New research suggests that consumers do care about durability—but it’s rarely top of mind when they’re making a purchase.
