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.
A school has 14 days to apply student-loan funds received from Sallie Mae to the borrower's account. The clock starts either when the school receives the funds or on the first day of classes. This is considered the official date of disbursement.
