Question

Construct a frequency distribution by exclusive method taking class interval of 10 for the following data : 12 37 17 53 58 26 21 19 50 42 27 6 42 56 47 32 15 21 30 16 43 16 8 23 37 36 42 18 6 37 10 25 12 33 47 52 41 32 50 11​

Answer 1

Answer:

(i) The class interval (40−49) has the highest frequency and the class interval (90−99) has the lowest frequency.

(ii) In the class interval (30−39), the lower limit is 30 − 0.5 = 29.5 and the upper limit is

39 + 0.5 = 39.5.

(iii) The range of the given distribution is 97− 32 = 65.
