What are medians and quartiles?
This custom study uses median and quartile values to compare your chosen hospital with the 100 Top Hospitals. Quartile values divide a sample of hospitals into four groups equal in number. The first quartile value (the 25th percentile) is the value for which 25 percent of the sample has lesser values and 75 percent of the sample has greater values. The 50th percentile (the middle, or median, value) is the value for which 50 percent of the sample has lesser values and 50 percent of the sample has greater values (the value that divides the sample into halves). The third quartile value (the 75th percentile) is the value for which 75 percent of the sample has lesser values and 25 percent of the sample has greater values.
