Ogive means a cumulative frequency curve for a given set of data. Depending on cumulative frequency, there are two types of ogive: Less than & More than. Less than Ogive: Less than Ogive Curve is plotted against respective upper limits of class interval. Less than Ogive Curve

- Take the cumulative frequencies along the y-axis (vertical axis) and the lower-class limits on the x-axis (horizontal axis).
- Against each lower-class limit, plot the cumulative frequencies.
- Connect the points with a continuous curve.

What is ogive in data analysis?
An ogive is a line plot of the cumulative frequency distribution against values of the random variable. Francis Galton coined the term ogive to describe the shape of the normal cumulative distribution function, as it has a form similar to the S-shaped Gothic ogival arch.
What shape is an ogive form?
equilateral archAn ogive or ogival arch is a pointed, "Gothic" arch, drawn with compasses as outlined above, or with arcs of an ellipse as described. A very narrow, steeply pointed ogive arch is sometimes called a "lancet arch". The most common form is an equilateral arch, where the radius is the same as the width.
What is ogive Class 10?
The Ogive is a graph of a cumulative distribution, which explains data values on the horizontal plane axis and either the cumulative relative frequencies, the cumulative frequencies or cumulative per cent frequencies on the vertical axis.
How many types of ogives are there?
two typesThere are two types of ogives : Less than ogive : Plot the points with the upper limits of the class as abscissae and the corresponding less than cumulative frequencies as ordinates. The points are joined by free hand smooth curve to give less than cumulative frequency curve or the less than Ogive.
What is an ogive plot?
An ogive graph serves as a graphical representation of the cumulative relative frequency distribution for quantitative variables. In other words, these graphs plot the percentile on the y-axis and the quantitative variable on the x-axis.
What are the uses of ogive?
Most Statisticians use the Ogive curve, to illustrate the data in the pictorial representation. It helps in estimating the number of observations that are less than or equal to the particular value. Ogives sometimes are formed the same as the frequency polygons.
What is an ogive quizlet?
An ogive is a graph that displays cumulative frequencies.
How are ogives formed?
Ogives are bands that form on some glaciers just below icefalls. The bands alternate in both height and color, and result from seasonal patterns. Darker bands form through increased melt and refreezing in the summer, when sediment collects on the glacier surface.
What is an ogive in architecture?
ogee or ogive : An arch with a pointed apex, formed by the intersection of two S curves usually confined to decoration and not used in arcade arches. Ogee arches were used only in the late Gothic period. Other types of arches:depressed, horseshoe.
How do you describe an ogive graph?
An ogive (a cumulative line graph) is best used when you want to display the total at any given time. The relative slopes from point to point will indicate greater or lesser increases; for example, a steeper slope means a greater increase than a more gradual slope.

Why ogives are mostly used in statistics?
An ogive graph is a plot used in statistics to show cumulative frequencies. It allows us to quickly estimate the number of observations that are less than or equal to a particular value.

What is an ogive?
In ballistics or aerodynamics, an ogive is a pointed, curved surface mainly used to form the approximately streamlined nose of a bullet or other projectile, reducing air resistance or the drag of air.

What is a traditional ogive?
The traditional or secant ogive is a surface of revolution of the same curve that forms a Gothic arch; that is, a circular arc, of greater radius than the diameter of the cylindrical section ("shank"), is drawn from the edge of the shan k until it intercepts the axis.
What is the ogive of a rifle?
Values of 4 to 10 are commonly used in rifles, with 6 being the most common. Another common ogive for bullets is the elliptical ogive. This is a curve very similar to the spitzer ogive, except that the circular arc is replaced by an ellipse defined in such a way that it meets the axis at exactly 90°.
Where did the word "ogive" come from?
The earliest use of the word ogive is found in the 13th century sketchbook of Villard de Honnecourt, from Picardy in northern France. The Oxford English Dictionary considers the French term's origin obscure; it might come from the Late Latin obviata, the feminine perfect passive participle of obviare, meaning the one who has met or encountered the other. However, Merriam-Webster's dictionary says it is from the "Middle English oggif stone comprising an arch, from Middle French augive, ogive diagonal arch".
What is an elliptical ogive?
An elliptical ogive is normally described in terms of the ratio of the length of the ogive to the diameter of the shank. A ratio of one half would be, once again, a hemisphere. Values close to 1 are common in practice. Elliptical ogives are mainly used in pistol bullets.
What is an ogive graph?
Answer: An ogive (oh-jive), which is called a cumulative frequency polygon sometimes, is also a type of frequency polygon that shows the cumulative frequencies. The Ogive graph also plots the cumulative frequency on the y-axis and the class boundaries along the x-axis.
How to construct an ogive?
To construct an Ogive, firstly, the cumulative frequency of the variables is calculated employing a frequency table. The result or the last number within the cumulative frequency table is usually adequate to the entire frequencies of the variables. Let us discuss one among the graphs called “Ogive” Here, we are getting to have a glance ...
What is the quiet or greater than cumulative series?
The frequencies of the succeeding classes are added to the frequency of a category. This series is named the quiet or greater than cumulative series. It is constructed by subtracting the primary class, second class frequency from the entire, third class frequency from that, and so on. The upward cumulative result is greater than or quite the cumulative series.
What is the Ogive?
Answer: Ogive, which is also known to be the cumulative frequency polygon, can be one among two other things: any hand-drawn graphic of a cumulative distribution function. any empirical cumulative distribution function.
What is a graph of a distribution?
The graphs of the distribution are frequency graphs that exhibit the characteristics of discrete and continuous data. Such figures are more appealing to the attention than the tabulated data. It helps to facilitate the comparison study for two or more frequency distributions. We can relate the form and pattern of the 2 frequency distributions.

Architecture
One of the defining characteristics of Gothic architecture is the pointed arch. This may have originated as in Sitamarhi caves in 3rd century BCE. The free-standing temple of Trivikrama at Ter in Maharashtra India dated to Satavahana period also contains ogive arch but it is constructed using principles of corbel.
