What's the difference between exiguity and exiguous?

Exiguity

Definition:

Example Sentences:

(1) Although data are exiguous, justifying neither acceptance nor rejection of the hypothesis that ANF functions physiologically to regulate body fluid volume and arterial pressure, the current evidence slightly favors acceptance.
(2) There was an increase in phenotype HLA-DR7 incidence, with respect to a non-selective population and a decrease of HLA-DR1, as it has already been mentioned in the literature, the variations were not statistically significant taking into account the exiguity of the samples considered.
(3) Also, since there is a diminutive capacity for trust and an exiguous chance to reach out or respond to significant others, external soothingness becomes unobtainable.
(4) It follows a retro-aortic course and its terminal distribution is exiguous, compensated by a coronary pattern of right predominance.
