The graphical distribution of the data is asymmetrical, indicating that the underlying population is not distributed normally This may indicate errors, data may need to be transformed or the study replicated, or alternate statistical analyses may be needed There are statistical measures of the degree of skewness, but they are not commonly used in the social sciences
A skewed distribution is not symmetric That is, it has different shapes on each side of the median For example
occurs when a squeegee travels with its lengthwise dimension at an angle that is not perpendicular to the direction of its travel Also called "snowplow "
A stone at the foot of the slope of a gable, the offset of a buttress, or the like, cut with a sloping surface and with a check to receive the coping stones and retain them in place
- In an imaging system it is when the document is scanned in crooked Some software and some scanners have a deskewing feature that corrects this problem
A measure, in hertz, of the difference between the actual frequency of a clock and what its frequency should be to keep perfect time See also ``drift''
Differences in the arrival times (or departure times) of signals in a parallel SCSI system Skew is caused by small delay differences in the paths of each SCSI signal including small differences in the length of the wire pairs Deskew delays in the timing specifications compensate for some skew Skew becomes ever more important with the tighter timing tolerances required by increasing data throughput
Crooked image appearance which occurs when the bit mapped image is not square with the page Generally this is caused by slippage or misfeeds during the scanning process
During printing or scanning, the contents of a page are almost never exactly verticle, which referred to as being skewed De-skewing is a process where the computer detects and corrects the skew in an image file
refers to the general shape of a distribution of scores when graphed as a frequency polygon There is zero skew when the shape of the distribution is symmetrical It is skewed when most of the scores are at one end of the distribution and very few are at the other end The tails of distributions are the areas at the extreme high or low end where the data tapers off to zero -- where the graph approaches the abscissa The skew is positive when the tail points in the positive direction and negative when it is pointing in the negative direction
A non-symmetrical distribution If, for example, most respondents on a ten-point scale rated the product a nine or ten, we would describe that distribution as "skewed "
If something is skewed, it is changed or affected to some extent by a new or unusual factor, and so is not correct or normal. The arithmetic of nuclear running costs has been skewed by the fall in the cost of other fuels Today's election will skew the results in favor of the northern end of the county
