Frequency  8 12 15 18 25 19 10
आलेख

उत्तर

Class Marks  Class Intervals Frequency 
16 12 – 20 08
24 20 – 28 12
32 28 – 36 15
40 36 – 44 18
48 44 – 52 25
56 52 – 60 19
64 60 – 68 10


Steps of construction: 

  1. Convert the class marks into class intervals. 
  2. Taking suitable scales, mark class intervals on x-axis and frequency on y-axis.
  3. Construct rectangles with class intervals as bases and corresponding frequencies as heights.
