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.

Why do we use ogives?

Statisticians use plots to illustrate data in pictorial form to make it easier to understand. 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.

Is ogive a line diagram?

An ogive is a special kind of line graph. This kind of graph looks just like a line graph, but think of an ogive as an “accumulated” line graph. Just like other types of graphs, an ogive does well at representing some kinds of data, and less well at representing others.

What is ogive Class 11?

Ogive or Cumulative frequency curve is the curve which is constructed by plotting frequency data on the graph paper, in the form of smooth curve.

How many types of ogives are there?

By joining the points the curve so obtained is called a cumulative frequency curve or ogive. There 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.

Does an ogive start at 0?

Plot the ogive The first coordinate in the plot always starts at a y-value of 0 because we always start from a count of zero. So, the first coordinate is at (10;0) — at the beginning of the first interval.

Does an ogive have to start at 0?

Plot the ogive The first coordinate in the plot always starts at a y-value of 0 because we always start from a count of zero. The second coordinate is at the end of the first interval (which is also the beginning of the second interval) and at the first cumulative count, so (20;5).

What is more than type ogive?

The Ogive is defined as the frequency distribution graph of a series. We will make a new table having a midpoint of the above given class and also having a column of cumulative frequency (greater than type) which is calculated as theory explained above. We have to add frequency and we get it as 60.

What is the shape of ogive curve?

First, representation of the ogive is a graph that contains a set of points that start from the origin, a smooth curve shaped like the letter S and is not closed. Second, the x axis is represented by a boundary and the y axis is represented by the cumulative frequency.

What are the two types of ogives?

There 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 a percentage ogive?

Ogives are used to determine the number, or percentage, of observations that lie above or below a specified value. For example, according to the table and the graph, 92% of the time the snow depth recorded in the 25-day period was below the 260 cm mark.

What is the meaning of the term ogive?

What is ogive – Definition and Meaning. Ogive : Ogive is the term named derived by the 13th-century itinerant master-builder named Villard de Honnecourt. In statistics, Ogives is the free hand graph to find how many data lies above or below the particular data. Its used for showing the graph of cumulative distribution function.

What can an ogive be used for in math?

Ogive in mathematics it comes under the part of statistics. It is a way to show the data in a single line. Representation of all the data with help of single line diagram. We can show an olive by graph. An ogive can be used to show the result at any time.

Which is the correct definition of the ogive curve?

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. Cumulative frequency is defined as the sum of all the previous frequencies up to the current point.

Which is an example of an ogive graph?

In statistics, Ogives is the free hand graph to find how many data lies above or below the particular data. Its used for showing the graph of cumulative distribution function. Example : Ordered Pair Orthogonal
