Ogive Ogive Basically graphs are used to represent frequency distributions or we can say graphs refer to the relationship between two variables. The most commonly used graphs are frequency distribution graphs. The graphs of frequency distribution are frequency graphs that are used to define the characteristics of both and these graphs are more appealing than the tabulated data to our eye. This helps us in the comparative study between discrete and continuous data that is two or more frequency distribution data's and its possible to compare two frequency data's according to their shape and pattern. The most commonly used frequency distributed graphs are below listed Histogram Frequency polygon Frequency curve

Ogives (used for the cumulative frequency curves) An ogive is an roundly tapered end of a two or three dimensional object. In aerodynamics an Ogive is a pointed surface or a curved surface and generally used to form the approximately nose of a projectile or bullet. A common ogive for bullets is the elliptical ogive. A secant ogive is a surface of revolution of the curve that forms the circular arch also named as Gothic arch having greater radius than the diameter of the cylindrical section. Mathematically it can be defined as “An ogive is a graph that refers the cumulative frequencies in a frequency distribution for the classes. An ogive shows the data below or above that a particular value.” There are two types of an ogive that are less than ogive and greater than ogive or more than ogive. In another words an ogive “can be defined as the frequency distributive graph of a series, these graphs are more appealing to eye and its easier to compare the study by using ogives.” In the statistics theory an ogive is a graph that shows the curve of a cumulative distribution function. The graph of the cumulative frequency distribution is also named as cumulative frequency curve or an ogive. Ogive basically describes the curved surfaces in architecture. Data may be represented by using a single line even. An ogive that is a cumulative line graph and is best used when one wants to display the total at any given time. The relative slopes from point to point will indicate greater or lesser increases in the slopes like for example a steeper slope refers the meaning a greater increase than a more gradual slope.

An ogive cannot be considered as ideal graphic that shows comparisons between categories because an ogive simply combines the values related to each category thus it refers to an accumulation means a growing or lessening total. In keeping track of a total and the individual values that are periodically combined then an ogive is an appropriate display. Understand about an ogive consider the following example. Example: If we saved 300 rupees in both the month February and the month March and 100 rupees in each of the months January, may and July then an ogive would show or display a running total. Although each individual monthâ&#x20AC;&#x2122;s savings could be represented in a bar chart, the total growth and loss cannot be measured as measured perfectly in an ogive. There are two ways to draw or construct an ogive or cumulative frequency curve. The curves usually have the â&#x20AC;&#x153;Sâ&#x20AC;? shape
