Steps :
1. On the x-axis , take 1 cm as 5 units and plot age .
2. On the y-axis , take 1 cm as 5 units and plot frequency.
3. Plot the points with coordinates having abscissae as actual limits and ordinates as the cumulative frequecies . In this case (10,0),(20,17),(30,42),(40,67),(50,100).
4. Join the points plotted by a smooth curve .
| Age less than | Cumulative Frequency |
| 10 | 0 |
| 20 | 17 |
| 30 | 42 |
| 40 | 67 |
| 50 | 100 |
