Analysis of a Stratified Random Sample in AFDC .

The article examines the significance of a stratified random sample in Aid for Dependent Children (AFDC) in the U.S. AFDC is considered to be one of the main welfare programs supported by the Department of Health, Education, and Welfare (HEW) along with its guidelines. The Quality Control System that measures the compliance of each state with AFDC procedures is considered to be the inherent part of the guidelines. It could be noted that a random sample of cases were audited to determine whether the benefits were based on a proper interpretation of the guidelines. The determination of error rates enables the federal administrators to locate the problem states. It also provides the HEW an estimate of over-payments used in the financial adjudication process.
