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

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%) --ron |
