Question

Tabulate The Following scores of 25 Students into a frequency distributions usibg an interval of 5 . 65 ,85,70,58,80,85,63,77,88,68,99,88,78,88,63,88,64,65,71,61,88,77,88,57,73​

Answer 1

Answer:

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?

ANSWER:

The frequency distribution table for the given scores can be drawn as:



(i) The frequency corresponding to the third class interval (30−40) is 9.

(ii) The size of each class interval is 10 and the midpoint of the class interval (30−40) is 

(iii) The range of the given scores is 64 − 12 = 52
