wrong bias: a bowl delivered where the biased side of the bowl has been placed opposite to the desired position for a given delivery. If a right handed player plays a forehand delivery, but has the biased side of the bowl on the right, the bowls bias will take an arc away from the intended target, and in most cases, outside the rink boundary.
Bowls are designed to travel a curved path because of a weight bias which was originally produced by inserting weights in one side of the bowl. The word bias itself is recorded as a technical term of the game in the 1560s. [10] The insertion of weights is no longer permitted by the rules and bias is now produced entirely by the shape of the bowl.
One side of the bowl has an indent or dimple allowing the player to identify by touch which side of the bowl has the bias. Crown green bowls come in a variety of bias strengths, weights, densities, sizes, materials and colours. The minimum weight is 2 lb (0.91 kg) but there is no maximum weight. [8] Bowls are referred to and sold by their ...

Short mat bowls is played indoors, so it is an all-year sport that is not affected by weather conditions. Because the equipment is transportable and easy to set up, it is particularly appropriate for locations that are also used for other purposes such as village halls, schools, and sports and social clubs; it is even played on North Sea oil rigs.
Until 1925 however, there was a need for bowls that took a consistent green. The answer came when English bowl manufacturer Taylor Rolph began to produce four inch lignum vitae bowls in sets of 16 that were guaranteed to take a consistent green. These are believed to be the first indoor bowls made specifically for the New Zealand market.
The funnel plot is not without problems. If high-precision studies are different from low-precision studies with respect to effect size (e.g., due to different populations examined) a funnel plot may give a wrong impression of publication bias. [4]
The advantage over 8-bit or 16-bit integers is that the increased dynamic range allows for more detail to be preserved in highlights and shadows for images, and avoids gamma correction. The advantage over 32-bit single-precision floating point is that it requires half the storage and bandwidth (at the expense of precision and range).
