Heights in Number of
(cm) plants
0.5 - 5.5 3
5.5 - 10.5 5
10.5 - 15.5 9
15.5 - 20.5 31
20.5 - 25.5 38
25.5 - 30.5 14
More than ogive: For 'more than ogive', we make the following cumulative frequency
table:
Heights (in Cumulative
cm) Frequency
0.5 or more 100
5.5 or more 97
10.5 or more 92
15.5 or more 83
20.5 or more 52
25.5 or more 14
30.5 or more 0
Thus, plotting the points (0.5,100), (5.5,97), (10.5,92), (15.5,83), (20.5,52),
(25.5, 14), (30.5,0) and joining these points by a free hand curve, we get the more than
ogive'
