The procedure is illustrated with following example
Draw a 'less than' ogive curve for the following data:
To Plot an Ogive:
(i) We plot the points with coordinates having abscissae as actual limits and ordinates as the cumulative frequencies, (10, 2), (20, 10), (30, 22), (40, 40), (50, 68), (60, 90), (70, 96) and (80, 100) are the coordinates of the points.
(ii) Join the points plotted by a smooth curve.
(iii) An Ogive is connected to a point on the X-axis representing the actual lower limit of the first class.
X -axis 1 cm = 10 marks, Y -axis 1cm = 10 c.f.
