Draw"less than type ogive for the given data in following table:
class interval | frequency
0-10 2
10-20 12
20-30 2
30-40 4
40-50 3
Answers
Step-by-step explanation:
Solution:-
Total number of frequencies = 23
On X -axis Taking Class upper boundaries and On Y-axis taking Less than cumulative frequencies to draw Less than Cumulative frequency curve.
Less than Cumulative frequency curve is also called Ogive Curve.
Class Intervals :-
0-10,10-20,20-30,30-40,40-50
They are Overlapping or exclusive classes
Upper limits are also upper boundaries .
Upper boundaries = 10,20,30,40,50
Frequencies :-
2,12,2,4,3
Less than Cumulative frequencies:
2,14,16,20,23
Scale :-
On X - axis 1 cm = 5 units
On Y -axis 1 cm = 2 units
Points to plot on the Graph Sheet:-
(10,2) ,(20,14) ,(30,16), (40,20) ,(50,23)
Observation:-
The graph of the given data is S -shaped Curve .
It is a raising curve.
