ASSERTION (A) : There are data restrictions in using Lorenz Curve since variable must be expressed as frequencies and negative values cannot be included.

REASON (R) : This technique is difficult to be applied to study of continuous variables.

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• (A) is true , but (R) is false.

• (A) is false , but (R) is true.

ASSERTION (A) : Partial correlation is a method of dealing with three or more variables.

REASON (R) : Basically, it is the correlation between two variables holding the third variables constant.

• 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.
