Question

Draw O-give for the following data class interval = 5-10,10-15,15-20,20-25,25-30,30-35,35-40. frequency = 1,2,4,0,3,5,6. cumulative frequency = 1,3,7,7,10,15,21. ​

Answer 1

Answer:

Class Interval Frequency

10-15 10

15-20 15

20-25 17

25-30 12

30-35 10

35-40 08

Steps of construction:

(a) Taking suitable scales, mark the class intervals on the x-axis and the frequencies on the y-axis.

(b) Construct rectangles with class intervals as bases and corresponding frequencies as heights.

(c) Join the mid-points of the rectangle to obtain the ogive.
