I need a formula (or other solution) that will pick out certain data in a
data set that is a particular value, and then calculate the median, 90th
and 10th percentile of this data. the only way i have been able to do it so
far is physically seperate the data, however this is tedious and
time-wasting, any tips/suggestions would be appreciated.

e.g
Data Set
5
1
9
.05
15
And i only want to process data 4

Try these **array** formulas.

To enter an **array** formula, hold down <ctrl<shift while hitting <enter.
Excel will place brackets {...} around the formulas.

Data is the range where your data exists. A1 is the particular value you want
to test against.

Median: =MEDIAN(IF(DataA1,Data))

10th Percentile =PERCENTILE(IF(DataA1,Data),10%)
90th Percentile =PERCENTILE(IF(DataA1,Data),90%)
