Skew partition

In graph theory, a skew partition of a graph is a partition of its vertices into two subsets, such that the induced subgraph formed by one of the two subsets is disconnected and the induced subgraph formed by the other subset is the complement of a disconnected graph. Skew partitions play an important role in the theory of perfect graphs. (Wikipedia).

Skew Lines, Perpendicular & Parallel Lines & Planes, Intersecting Lines & Transversals

This geometry video tutorial provides a basic introduction into skew lines. It explains the difference between parallel lines, perpendicular lines, skew lines, intersecting lines, and transversals. Parallel lines are coplanar lines that do not intersect. Skew lines are noncoplanar lines

Determining Skewness In Ogive Graphs

I help you identify left skewness, right skewness, and bell curves in an Ogive graph. At 6:40 I said "this is left skewed"- that is incorrect. Skewness is determined by the direction of the tail. In the histogram, the tail tapers off to the right, so it is right skewed. Check out http://w
