Question

To draw a histogram to represent the following frequency distribution:

the adjusted frequency for the class 25-45 is :

(A) 6

(B) 5

(C) 3

(D) 2

Answer 1

(D) 2

Explanation:

Adjusted frequency of a class is given by,

(Minimum class size of frequency distribution × Frequency of given class) / Class size of given class

Therefore,

Adjusted frequency for the  class 25 – 45 = (5 × 8) / 20 = 2

Hence, option (D) is the correct answer.
