The advantages of this are: (i) T, that each subject has an equal chance of assignment to any, intervention under the study trial, (ii) to produce comparable, groups and to attain validity for statistical tests, and (iii) to, ensure that the groups are alike in all important aspects and, differ only in intervention each group receives. There are random sampling methods to draw samples that adequately represent a cross-section of the entire population. Sensitivity, useful to identify or to rule out the disease and indicate the, inherent quality of the test. The sample so obtained should be random in nature.
