Construction of Ogive of less
than type
The smooth curve drawn between
the upper limits of class intervals and cumulative frequency
is called cumulative frequency curve or ogive (of less than type)
The upper limits of the intervals and cumulative frequency are
shown in the above table
The method of drawing an ogive of less than type is as
follows
(1) Firstly we draw two perpendicular lines, one is horizontal
(x-axis) and the other is vertical (y-axis), on a
graph
(2) Now, we mark the upper limits on the horizontal line and the
cumulative
frequencies on the vertical line by taking suitable scale
(3) After this, we plot the points These are the
points corresponding to the upper limit and the cumulative
frequency
(4) Now, we join these points to obtain a smooth curve
Construction of Ogive of more than type
The smooth curve drawn between the lower limits of
class intervals and cumulative frequencies is called cumulative
frequency curve or ogive (for more than type)
The method of construction of more than type ogive is same as
the construction of less than type For more than type ogive,
we take the lower limits on x-axis and the cumulative
frequencies on the y-axis In the above table, the lower
limits and the cumulative frequencies have been represented
The ogive of more than type is obtained by plotting the
points
