The document explains how to plot a more than cumulative frequency ogive curve. It involves starting from the lower limit of class intervals and subtracting frequencies to get cumulative frequencies. The points are then plotted on a graph with the upper limit of classes on the x-axis and cumulative frequencies on the y-axis. These points are connected with a smooth curve to show the ogive. An example is provided of data to construct a more than cumulative frequency and plot the corresponding ogive.

5. How to plot an ogive
curve?

6. Following steps are necessary to plot a more
than type ogive curve ;
1. Starts from the lower limit of the class
intervals and total frequency is subtracted
from the frequency to get the cumulative
frequency distribution .
2. In the graph , consider the lower limit x -
axis direction and cumulative frequencies
along y - axis direction .

7. 3.Plot the points x, y, where ‘x’ is
the upper limit of theclass and
y is the corresponding
cumulative frequency.
4. Joins the points by a smooth
curve.
