Quartiles. Five data points denoting the distribution or spacing of data in a dataset. By convention, these data points are labeled Q0 through Q4, with Q0 representing the smallest value in the dataset, and Q4 the largest value in the dataset. Q2 represents the median value of the data and Q1 and Q3 the median values for each half of the data. The quartiles disclosed by Ginnie Mae are weighted by aggregated RPB.
