Consider the following figures X and Y :

            

• Figure X is small-scale map and distance between A and B is 40 metres.

• Figure Y is large-scale map and distance between C and D is km.

• Figure X is large scale map and figure Y is small-scale and distance between A and B and C and D are 40 metres and 20 km respectively.

• Figure X is large scale and Figure Y is small-scale . The ground distance between A and B and C and D.

ASSERTION (A) : Dot map is especially useful when the values are disturbed unevenly and sporadically.

REASON (R) : Smaller the statistical unit , more accurate is the Dot Map.
