Median	Another measure of central tendency. The median, is the exact middle of the range of ranked data points. For example, in a distribution of 11 salaries, the median is the 6th highest case. 5 cases fall below its value and 5 cases are above its value. The median is by definition equivalent to the 50th percentile. Percentiles are explained below.
Percentiles	Percentile is a statistical calculation based on the distribution of data points using a formula which defines the lowest case as 1% and the highest case as 100%. The rank order of the cases is between 1 and 100 percent and are then divided into equal intervals. For example:

25th	At the 25th percentile, 25% of the data falls below this point and 75 % of the data is above this point.
50th	The median. 50% of the data is below and 50% of the data is above the median. Where there is an even number of data points, the two middle data items are averaged.
75th	At the 75th percentile, 75% of the data falls below this point and 25 % of the data is above this point.
