Ogive. An Ogive (pronounced O-Jive) is a graph that represents the cumulative frequencies for the classes in a frequency distribution and it is a continuous frequency curve. Ogive has the shape of an elongated 'S' and is sometimes called a double curve with one portion being concave and the other being convex.
Given a connected graph G, a connected subgraph that is botha tree and contains all the vertices of G is called a spanning tree for G.DiscussionGiven a connected graph G, one is often interested in constructing a connectedsubgraph, which contains all of the vertices of G, but has as few the edges of G aspossible. graph is connected if and only if it has a spanning tree.DiscussionOne of the key points of Theorem 5.4.1 is that any connected graph has a spanningtree. A spanning tree of a connected graph can be found by removing any edge thatforms a simple circuit and continuing until no such edge exists.
