----------------
-- PERCENTILE --
----------------
Percentile is the value at which a certain percentage of values in an array fall below that value, and a certain percentage of values fall above. For example, looking for the 80th percentile means finding a value at which 80% of the values in the array fall below that value, and therefore 20% of the values in the array fall above.
The formula is PERCENTILE(range of values in your array, the percentile you're looking for). The percentile value is expressed as a decimal between 0 and 1 showing the percentage you're looking for: for instance, 0.5 is looking for the 50th percentile, 0.9 is looking for the 90th percentile, etc.
In this example it will calculate the value at which 75% of the values in the array are below that value (and therefore 25% of values are above). The result will be a number such as 2013.12, which means that 75% of values in column Q will fall below 2013.12, and $25% of values in column Q will fall above 2013.12.
=PERCENTILE(Q:Q,0.75)
or
=PERCENTILE.EXC(Q:Q,0.75)
------------
-- MEDIAN --
------------
MEDIAN is bascially a percentile looking for the value of the 50th percentile (half of the values fall above, half of the values fall below). Therefore,
=MEDIAN(Q2:Q19)
gives the same results as
=PERCENTILE(Q2:Q19,0.5)
-----------------
-- PERCENTRANK --
-----------------
-- PERCENTRANK shows at what percentile each value in a range falls. This can be helpful when splitting values into deciles or quantiles.
For example, if you start with these values in your array:
Row Value
1 $39,541,385.16
2 $8,707,780.00
3 $1,110,000.00
4 $737,600.00
5 $614,544.08
6 $558,448.00
7 $509,800.00
8 $414,039.74
9 $405,000.00
10 $394,100.00
11 $388,746.40
12 $379,000.00
13 $365,439.98
14 $328,682.50
15 $306,800.00
16 $260,000.00
17 $249,779.70
18 $240,000.00
-- PERCENTRANK will return percentile values for each value.
=PERCENTRANK(Q:Q,Q3,2) (format is PERCENTRANK(span of array, value you're testing, and number of decimal places you want to include - it'll round the decimal)
Row Value Percentile
1 $39,541,385.16 1
2 $8,707,780.00 0.9
3 $1,110,000.00 0.8
4 $737,600.00 0.8
5 $614,544.08 0.7
6 $558,448.00 0.7
7 $509,800.00 0.6
8 $414,039.74 0.5
9 $405,000.00 0.5
10 $394,100.00 0.4
11 $388,746.40 0.4
12 $379,000.00 0.3
13 $365,439.98 0.2
14 $328,682.50 0.2
15 $306,800.00 0.1
16 $260,000.00 0.1
17 $249,779.70 0
18 $240,000.00 0
- You can then use a SWITCH formula or a lookup table to assign deciles based on the percentiles that you get from PERCENTRANK
=SWITCH(C2,1,10,0.9,10,0.8,9,0.7,8,0.6,7,0.5,6,0.4,5,0.3,4,0.2,3,0.1,2,0,1)
Row Value Percentile Decile
1 $39,541,385.16 1 10th decile
2 $8,707,780.00 0.9 10th decile
3 $1,110,000.00 0.8 9th decile
4 $737,600.00 0.8 9th decile
5 $614,544.08 0.7 8th decile
6 $558,448.00 0.7 8th decile
7 $509,800.00 0.6 7th decile
8 $414,039.74 0.5 6th decile
9 $405,000.00 0.5 6th decile
10 $394,100.00 0.4 5th decile
11 $388,746.40 0.4 5th decile
12 $379,000.00 0.3 4th decile
13 $365,439.98 0.2 3rd decile
14 $328,682.50 0.2 3rd decile
15 $306,800.00 0.1 2nd decile
16 $260,000.00 0.1 2nd decile
17 $249,779.70 0 1st decile
