What is a Decile?

In statistics, a decile is any of the 10 values that divide the sorted data into ten equal parts, so that each part represents 1/10 of the sample or population. For example, to be in the first decile is to be in the top 10% of the group based on an ordering.
Below, stocks are ranked from lowest P/E ratio to high and the top 10% of lowest P/E ratios are green while the stocks with the highest 10% of P/E ratios are red.
The order is however arbitrary. We rank low P/E ratio stocks as green becuase they are "cheaper" and have more "value". For the same reason, EBITDA/EV is ranked from largest to smallest as a larger number indicates more value.
