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.
I've applied for FAFSA and will take out Govt' loans, but, I still cannot afford most of the tuition which is around 130k overall. Therefore, I chose to take out private student loans of 48k from Sallie Mae and chose Variable Interest at around 9%. I'm deeply worried that I chose variable rate instead of the Fixed rate at around 11.5%.
