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.
Moreover, many students first get involved with major finances â such as student loans â during their undergraduate years, adding to the responsibility of being a college student. Sallie Mae helps simplify the process of financing an undergraduate education, with a selection of competitive private student loans.
