The following data : 2, 5, 15, 25, 20, 12, 8, 7, 6, 16, 21,17, 30, 32, 23, 40, 51, 15, 2, 9, 57, 19, 25 is grouped in the classes 0 –5, 5 –10, 10 –15 etc. Find the frequency of the class 20 –25.

The marks obtained (out of 20) by 30 students of a class in a test are as follows: 14, 16, 15, 11, 15, 14, 13, 16, 8, 10, 7, 11, 18, 15, 14, 19, 20, 7, 10, 13, 12, 14, 15, 13, 16, 17, 14, 11, 10, 20. Prepare a frequency distribution table for the above data using class intervals of equal width in which one class interval is 4-8 (excluding 8 and including 4).

Let the marks obtained by 30 students of a class in a test be 38, 26, 4, 32, 20, 22, 11, 47, 12, 23, 8, 2, 10, 8, 12, 17, 2, 19, 16, 42, 40, 13, 47, 38, 17, 27, 30, 6, 23, 18. Arrange the data in grouped frequency distribution, using groups 0-10, 10-20 e tc.

the daily minimum temperatures in degrees Celsius recorded in a certain Arctic region are as follows: -12. 5 ,-10. 8 ,-18. 6 ,-8. 4 ,-10. 8 ,-4. 2 ,-4. 8 ,-6. 7 ,-13. 2 , -11. 8 ,-2. 3 , 1.2 , 2.6 ,0,-2. 4 ,0, 3.2 , 2.7 , 3.4 ,0,-2. 4 ,-2. 4 ,0, 3. 2 , 2.7 , 3.4 ,0,-2. 4 ,-5. 8 ,-8. 9 ,-14 ,6,-12. 3 ,-11. 5 ,-7. 8 ,-2. 9 Represent them as frequency distribution table taking -19. 9\ to-15 as the first class interval.

From a grouped frequency distribution from the following data by inclusive method taking 4 as the magnitude of class intervals. 31,23,19,29,22,20,16,10,13,34, 38,33,28,21,15,18,36,24,18,15, 12,30,27,23,20,17,14,32,26,25 18,29,24,19,16,11,22,15,17,10
