Q. 1 B

Find the range and coefficient of range of the following data.

41.2, 33.7, 29.1, 34.5, 25.7, 24.8, 56.5, 12.5

Answer :

Given the set of data 41.2, 33.7, 29.1, 34.5, 25.7, 24.8, 56.5, 12.5.


Let the maximum value in the data set be denoted by xmax and minimum by xmin


Range = Maximum value in the data set – Minimum value in the data set


= xmax - xmin


= 56.5 – 12.5


= 44


Range R = 44


Let the Coefficient of Range be denoted by s.


s =


=


=


= 0.637≈0.64


s = 0.64
