Following data represent the marks obtained by 100 students of a class...Draw both the ogives for the data given above.Also find the median of the data with the help of a graph...
Answers
Median from graph is approx 24
Step-by-step explanation:
Question data attached :
Class f cf1 cf2
0-5 4 4 100
5-10 6 10 96
10-15 10 20 90
15-20 10 30 80
20-25 25 55 70
25-30 22 77 45
30-35 18 95 23
35-40 5 100 5
Median from graph is approx 24
Median = 20 + 5 * (50 - 30)/25
= 20 + 4
= 24
Less than ogive
The points with the upper limits of the class are plotted on x axis and the corresponding less than cumulative frequencies on y axis.
The points are joined by free hand smooth curve to give less than cumulative frequency curve or the less than Ogive
More than ogive
The points with the Lower limits of the class are plotted on x axis and the corresponding more than cumulative frequencies on y axis.
The points are joined by free hand smooth curve to give more than cumulative frequency curve or the More than Ogive
