Includes Wake

Presentation Graphics from Polygon can also be clearly described a data. Polygon is an Includes Wake contains much that is closed, whereby to close the polygon is needed an additional hose on both ends of the distribution with zero frequency. If we want to compare two groups of data for example the size is not equal to making two frequencies polygon on one image, then we must use the relative frequency or percentage and called the Relative Frequency Polygon or Polygon Percentage.

Another line graph called Cumulative Frequency Polygons or Ogif obtained by making a cumulative frequency plot which is smaller than the upper limit of the upper class grade, and then connecting all consecutive points with straight lines. If that is used is the relative cumulative frequency or percentage, then the graph is called the Relative Frequency Ogif or Ogif Percentage.

Graphs described above is an example of examples of graphs that usually used in statistics that explain the way the description of the data through a form of Presentation Graphics.
