1.	The marks obtained by 40 students of class IX in an examination are given below: 23,5,12,16,8,6,12,8,18,2,16,10,2,23,7,9,12,20,0,3,5,16,18,3,17,7,23,18,13,10,21,7,1,24,20,15,13,21,13,5. Present the data in the form of a frequency distribution using the same class size, starting with class 0-5 (where 5 is not included.)
Answer» Solution :Minimum observation is 0 and MAXIMUM observation is 24. The classes of EQUAL size covering the GIVEN DATA are: 0-5, 5-10, 10-15, 15-20 and 20-25. Thus, the frequency DISTRIBUTION may be given as under:
