Question

Given below are the marks obtained by 40 students in an examination:

29	45	23	30	40	11	48	01	15	35
40	03	12	48	49	18	30	24	25	29
31	32	25	22	27	41	12	13	02	44
07	43	09	49	19	13	32	39	25	03

Taking class intervals 1 – 10, 11 – 20, ..., 41 – 50, make a frequency table for the above distributions and draw a histogram to represent it.

Answer 1

Here is the histogram representing the marks obtained by 40 students. Each bar shows how many students scored within each class interval:

1 – 10: 6 students

11 – 20: 8 students

21 – 30: 11 students

31 – 40: 7 students

41 – 50: 8 students
