For a symmetric distribution (where the median equals the midhinge, the average of the first and third quartiles), half the IQR equals the median absolute deviation (MAD). The median is the corresponding measure of central tendency. Identification of outliers (see below).
SLM Corporation (commonly known as Sallie Mae; originally the Student Loan Marketing Association) is a publicly traded U.S. corporation that provides consumer banking. Its nature has changed dramatically since it was set up in 1973. At first, it was a government entity that serviced federal education loans.
Some schools allow a student to request that Sallie Mae disburse the student's funds directly to her and not to the school. In this case the school may either issue a check, send an electronic transfer, pay the student in cash or sign over Sallie Mae's loan check to the student. Because both the school and the student are often listed as beneficiaries on loan checks, the signatures of both may be required to release the funds.
