It presents a curve that is asymmetrical and has a tail extending toward the right (positive skew) or to the left (negative skew). Skewness also means that the mean, median, and mode of a data set do not share the same value and are all different. How do you measure skewness?
- statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can...- In geometry, a skew polygon is a closed polygonal chain in Euclidean space. It is a figure similar to a polygon except its ...

The rule of thumb is that with a right skew, the mean is usually to the right of the median. However, like most rules of thumb, there are exceptions. Most distributions with right skew you come across in elementary statistics will have the mean to the right of the median. The Journal...
People are sometimes less comfortable with asymmetrical distributions, but they are a fact of life in some subject areas. They have logical reasons for occurring, such as when natural limits skew the results away from the boundary. We’ll get to that shortly. ...

Are skew lines parallel planes? A plane is defined by three points, while a line is defined by two. A single line, then, can be in any number of different planes. By definition, two skew lines exist in different planes, but they are still lines. The two planes containing two skew lin...
