Decile


 * In descriptive statistics, a decile is any of the 9 values that divide the sorted data into 10 equal parts, so that each part represents 1/10th of the sample or population. Thus:
 * The 1st decile cuts off lowest 10% of data, i. e., the 10th percentile.
 * The 5th decile cuts off lowest 50% of data, i. e., the 50th percentile, 2nd quartile, or median.
 * The 9th decile cuts off lowest 90% of data, i. e., the 90th percentile.
 * See Fisher's method for an example.
 * In astrology, a decile is an aspect of 36 degrees. It is one-tenth of the 360 degree circle that forms our zodiac.  The decile is regarded by astrologers as a mildly beneficial aspect.
