Draw a histogram to represent the following frequency distribution.

The marks scored by 40 candidates in an examination (out of 100) is given below:

75, 65, 57, 50, 32, 54, 75, 67, 75, 88, 80, 42, 40, 41, 34, 78, 43,

61, 42, 46, 68, 52, 43, 49, 59, 49, 67, 34, 33, 87, 97, 47, 46, 54,

48, 45, 51, 47, 41, 43.

Prepare a frequency distribution table with the class size 10.

Take the class intervals as (30-39), (40-49), ... and answer the following questions:

(i) Which class intervals have highest and lowest frequency?

(ii) Write the upper and lower limits of the class interval 30-39

(iii) What is the range of the given distribution?

Prepare the frequency distribution table for the given set of scores:

39, 16, 30, 37, 53, 15, 16, 60, 58, 26, 28, 19, 20, 12, 14, 24, 59,

21, 57, 38, 25, 36, 34, 15, 25, 41, 52, 45, 60, 63, 18, 26, 43, 36,

18, 27, 59, 63, 46, 48, 25, 33, 46, 27, 46, 42, 48, 35, 64, 24.

Take class intervals as (10-20), (20-30), ... and answer the following:

(i) What does the frequency corresponding to the third class interval mean?

(ii) What is the size of each class interval? Find the midpoint of the class interval 30-40.

(iii) What is the range of the given set of scores?

Draw a histogram to represent the following frequency distribution.
