ASSERTION (A) : Area sampling by random numbers requires the area under study which should be gridded within two areas at right angle.
REASON (R) : The intersections of row and coulmn of the area will give the sample locations of observations in the area.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true , but (R) is false.
(A) is false , but (R) is true.
