Whereas statistics and data analysis procedures generally yield their output in numeric or tabular form, graphical techniques allow such results to be displayed in some sort of pictorial form. Analysis Statistics. More formally a Graph can be defined as, A Graph consists of a finite set of vertices (or nodes) and set of Edges which connect a pair of nodes. Adjacency lists are generally preferred because they efficiently represent sparse graphs. The vertex set partitions are then distributed to the PEs with matching index, additionally to the corresponding edges. Learn a new word every day. Overview.

The parallelization of graph problems faces significant challenges: Data-driven computations, unstructured problems, poor locality and high data access to computation ratio. p A bar graph is a chart that plots data using rectangular bars or columns (called bins) that represent the total amount of observations in the data for that category. Every PE has its own subgraph representation, where edges with an endpoint in another partition require special attention. Poorly chosen representations may unnecessarily drive up the communication cost of the algorithm, which will decrease its scalability. Partitioning the graph needs to be done carefully - there is a trade-off between low communication and even size partitioning[10] But partitioning a graph is a NP-hard problem, so it is not feasible to calculate them. This bounds the amount of communication partners for each PE to ... Help them in sourcing the statistics. Glossary of Statistical Terms You can use the "find" (find in frame, find in page) function in your browser to search the glossary. Ask them to mark the title, axis, scale and label the graph well. [citation needed] In the matrix representations, the entries encode the cost of following an edge. This is far too many to print out in a journal article or sidebar of a magazine story. × The chart is divided into sectors, where each sector shows the relative size of each value. , where Definition: A graph in which successive points representing the value of a variable at selected values of the dependent variable are connected by straight lines. In the most common form of histogram, the independent variable is plotted along the horizontal axis and the dependent variable is plotted along the vertical axis. Bar Graphs.
