Range is the
(a) difference between the largest and the smallest observations
(b) difference between the smallest and the largest observations
(c) average of the largest and the smallest observations
(d) ratio of the largest to the smallest observation
The option (a) is correct.
Range is defined as the difference between the largest and the smallest observations.
Algebraically,
R = H – L
Where,
R denotes range
H is the highest value
L is the lowest value
