A bar graph is usually used when one would like to compare the frequencies of the different components. By using a bar graph, it is very evident which is the highest, the lowest etc.\n\nA pie graph is used to show the proportion of the different components of the total frequency. You can tell immediately which is the majority when you use this, but you cannot really tell at first glance when you use a bar graph.

It is a map of which "departments" report to which departments as well as who reports to whom.\n\ne.g.   VP of Finance & VP of IT & Admin Assistant to President report to the President.\n\nthen all managers who report to VP of Finance show up underneath him.\n\nYou can find an example here: http://www.european-patent-office.org/epo/an_rep/2001/images/gifs/org_structure.gif

There is the so called PC based, popular application used is MS Project, I will assume that you have tried your hand on this already.\n\nThere is also a collaboration type like MS Sharpepoints.\n\nThen there is the network based, like Agile, corporate user can define what are needs, requirements and task management in this system, its a customize application.\n\nAs for techniques, there are those who follows the MS Project schedule, there are those who refer to Gantt chart, then there are experience folks [including me] who rely on the ability to visualize the whole project, delegates and identify bottleneck, without using paper or notes.

We can use graphs to create a more meaningful and visual representation of data.  For instance, pie charts represent the percentage of a data set (51% white, 49% black).  Line graphs can show trends (the rising sales of hybrid vehicles vs. the falling sales of gas-guzzling vehicles).

The network diagram shows the logical sequence of tasks ie the dependencies between the tasks.  It doesn't reflect timing directly, (two boxes one above the other may or may not be executed at the same time) although dates can be included in each box of the network.\n\nSince the network diagram is more like a flowchart, it's a useful communication tool, and it's easier to understand things like why the critical path is where it is.  \n\nA variant that is sometimes used is the time-phased network diagram, where the boxes are arranged along a date scale, normally according to the start date.\n\nA "proper" Gantt chart does not show dependencies, although many people try to superimpose dependencies onto their Gantt charts, often resulting in a unreadable mess.\n\nWhile most PM tools do a reasonable job of drawing a Gantt chart, they often don't do such a good job of drawing a clean looking network diagram.  There are add-ons tools that you can buy to extract data from your application and do a better job of drawing the network.

The Lorenz curve is a graphical representation of the cumulative distribution function of a probability distribution; it is a graph showing the proportion of the distribution assumed by the bottom y% of the values. It is often used to represent income distribution, where it shows for the bottom x% of households, what percentage y% of the total income they have. The percentage of households is plotted on the x-axis, the percentage of income on the y-axis. It can also be used to show distribution of assets. In such uses, some political doctrines (e.g. socialism) consider it to represent social inequality.\n\nAnd below is a link to how it is used for credit scoring. Its a little complex so if you need any help give me a shout.\nhttp://66.249.93.104/search?q=cache:KML8OQmRuygJ:www.itwm.fhg.de/fm/projects/rating/uKKM.pdf+lorenz+test+credit+scoring&hl=en&gl=uk&ct=clnk&cd=3&client=firefox-a\n\n\n\n\nHiya, in reply to ur e-mail:\nHiya, glad I could help. Try these links theres a lot of information there about lorenz dominance:\n\nhttp://www.st-andrews.ac.uk/crieff/dp0505.pdf\n\nand for the tests themselves for Lorenz dominance I found this article particularly helpful:\nhttp://repec.org/esAUSM04/up.26369.1078184646.pdf\n\nand as a guide:\nhttp://www.stat.fi/isi99/proceedings/arkisto/varasto/jntt0559.pdf\n\nI tried to e-mail you it but yahoo said it couldn't because it couldn't confirm your e-mail.
