The challenge – Adding Percentile Information
Let’s get back to our last week’s KPI dashboard example: Adding sort options to excel dashboards. In today’s post we want our dashboard to take a step forward by adding another data analysis feature. Up to now the user is able to view a window of 10 rows out of a much larger list and to sort by any given decision parameter. But the KPI dashboard falls short if we want to evaluate the performance of the displayed items regarding the other 4 KPIs.
Imagine we are at the top of the list and the table is sorted by KPI 1 (see left). We see that “Product Name 36” is the TOP performer regarding KPI 1. But how does it perform regarding KPI 3? The value of 2% is probably rather poor, but how poor? Sure, we can change the sort order to KPI 3 and scroll down until we find product 36 and look at the ranking in the first column. But changing the sort order back and forth is in-convenient, time-consuming and not user-friendly.
The solution
One statistical method to examine a list of data is the percentile. A percentile is the value of a variable below which a certain percent of observations fall (more). The 10% percentile of our list of values for KPI 3 returns the threshold at which 10% of all values are smaller than this threshold. We will use this method to classify the values of the KPIs that are not selected as the sort criteria by highlighting the values above the 90% percentile in green (10% best performers) and by highlighting the values below the 10% percentile in red (10% poorest performers).
After the highlighting we are now able to see immediately that Product 36 is best in class regarding KPI 1 but it belongs to the poorest 10% of all products regarding KPI 3.
Download the Excel file with KPI Dashboards and read on below how it is done.
The implementation
Implementation needs a simple conditional formatting and the excel spreadsheet function PERCENTILE. The syntax of this function is PERCENTILE (array, k), where ‘array’ is the range with the data and ‘k’ is the percentile value in a range between 0 and 1. PERCENTILE (A1:A100, 0.10) returns the threshold at which 10% of all values in the range are smaller than this value and the remaining 90% are larger than this value.
Here is the description how to change the workbook:
- Add two additional rows to the data worksheet to define the upper and lower percentile value.
- Insert five new columns on the dashboard each of them right to the existing column with the data.
- To simplify the formula, insert the number of each KPI in the cells below the header (F6 = 1; H6 = 2, and so on).
Fill the new columns with the following formula (example for cell G8):=IF (mySortCriteria=F$6,"",
IF (F8>PERCENTILE (Calculation!$K$10:$K$109,Data!$E$5),"<+",
IF (F8<-","")))If the actual column is the one the table is sorted by, a blank would be returned. Otherwise: if the value
in the cell left is larger than the e.g. 90% percentile, “<+”, if the value is smaller than the 10% percentile “<-” will be returned. For all other values the result of the formula is a blank.
Format the new columns with a red font color and add additional formatting that changes the font color to green if the cell value is “<+”.- Finally add a caption under the table to help the user understand what the triangles are representing.
Final remarks
If you don’t like the triangles, you could easily replace them by a dot or a diamond or whatever you choose. Or you might want to change the colors or put the triangles to the left of the columns instead of the right. If you don’t like the extra columns next to the data, you could also use the described formula to conditionally format the cells with the data (e.g. with red and green fill color).

Up to now we have limited our dashboard to texts and numbers. Of course graphical visualization can always add much value for analysis. See next post: Part 4: Add Microcharts to KPI Dashboards

Hi Chandoo, I need you help in the following problem.
I'm trying to get a direccion from a found result. With this dirreccion I will want the before cell value. For example, If result of a find is 38 localized in cell $C$2, I need to get previus value (cell $B$2 ), maybe Andrés.
Do you know some way to do that?
Thank you for you help.
Hi Chandoo
Thanks for this. One thing though: In my pre-2007 version of Excel, the COUNTIF function doesn't recognise a semicolon (;), but requires a comma.
Is the semicolon an Excel 2007 thing?
Jair... I am not sure I understand what you want. what do you mean by Dirreccion?
@Lincoln: I am sorry, often I forget that I am using European version of excel where the delimiter is ; instead of ,. I have corrected the formula now.
Thanks for this nice tip, i used to do a find all after filling every new items which was cumbersome.
Do you know a way to extend this validation search to other tabs/sheets ?
Thanks for you attention. I'm trying to get of value continue from a found value. Let me show a example:
Name Years
John 35
Maria 28
Teresa 32
If I search the max years, the result is 35, but I need that result to be John. Do you know how I can do it?
@Subbu.. you can easily extend the validation to other sheets by pasting the data validations. See the latest article here: http://chandoo.org/wp/2009/10/28/copy-data-validations/
@Jair.. you can use the large() or small() formulas to do this. for eg. =index(A1:A3,large(B1:B3,1)) will get you the name of the person with highest "years". More help here: http://chandoo.org/excel-formulas/large.html
Hi, I don't know if I'm using bad the formula or its performance is diferent for my Office version. Large() formula return the value in the cell, in my example 35. The index() formula use a range, row and column. I'm using the large() as number of row, and it is bad because into the range don't have row 35. This is my perception. What do you think?
Hi, I going to prove, with this solution by JLD http://jldexcelsp.blogspot.com/2008/07/extraer-direccion-de-celda-en-matriz.html
Hello,
I am trying to attempt data validation in Excel Mobile, but the DV tool isnt available. I want to prevent duplicates is all, any advice on acheiving this in Excel Mobile? Thanks..
@Jair... my french aint that good. it starts at "merci" and ends at "beau coup".
Anyhow, you need to merge the large with vlookup to do this. I am not sure if you have solved the problem. Otherwise let me know with details and I can write the formula in comments.
@Chad... I have never used excel mobile, so I have no idea. May be they have not implemented data validations in excel mobile.
Any excel mobile users out there?
Hi Chandoo, the proposed solution by JlD is interesting. He created a macro to get values when the matrix is not one dimensional, how on my problem. This fuction for me.
I would like to share you my work, how can I upload?
@Jair.. sorry for such a delayed reply.. you can upload the files to skydrive and link them here. Or you can email them to me at chandoo.d @ gmail.com and I will upload them somewhere. But it could take forever if you email files to me as I am a bit lazy.

Hi,
Can you help me in Microstrategy?
Br,
Moin
really wonderful article. I feel it is implementing Primary Key concept into spreadsheets.
Hi article on data validation. Excel is a very versatile platform to work with and we use it for all kinds of data tabulation. In fact this must have been the most rudimentary data management tools I must have worked with and knowing such tips only adds functuionality to our user experience. Great article. looking forawrd to read more.
Hi Chandoo,
Thanks for such a nice idea.
I tried copy paste the data into the validated area, but the pop-up msg (warning msg) doesn't came. Is it something that we need to update the data manually each time,.
Do we have any option where we can bulk upload the number and it throws a warning message that the data already exits and do we want to continue with this ?
Please do reply me.
Thank you.
Regards,
Vasanth.
It was really useful chandoo...thanks a lot...
Tried this in excel 2010 and it did not work?
Could the newer excel have changed that much?
@Leo
It works fine in Excel 2010
The formula used above =COUNTIF($B$4:$B$11,B4)<=1
only applies to the range B4:B11
Did you adjust the range to your data?
This page helped me accurately to find solution of my question. thanx
we want to prevent duplicate entries in three columns combined, using data validation, i.e. say, column A has first name and Column B has middle name, Column C has last name. the first name can be duplicate, middle name can be duplicate, last name can be duplicate, but not all three at the same time.

Hi, I've tried above validation method to prevent duplicate value from entering into the cells. It's work, when user key in the data into the selected range. However, it's not working when user copy-&-paste the info into the same range.
Please advice. Thanks.
Hi Chandoo,
Does it work in Excel 2007?
Please Reply
thanks chandoo........
it does not work when data is copy pasted...any solution for this??
hi i m shaloo and i want to know in excel if i write duplicate no.then it says or show about we are write duplicate no.
Hi Chandoo
I've tried using this with a Named Range, which is actually a column in a Table as DV wont accept a table reference, and it wont work.
Also tried using Offset to specify the Named Range, but that wont work either.
Is it possible to use Named Ranges with DV?
Thanks
Kris
I have tried the above formula on a table column. The Error box does not pop up, there is only the small ! next to the cell with the duplicate. The column I am working with is formulas that produce a date. Is the reason it doesn't work that the cells contain formulas rather than data?
The formula works but only if I enter data in cell above it. So for example, if I have "123" in B11 it does not allow me to enter "123" in B10, B9, B8, etc. But I can still enter "123" in B12. Please help! 🙂
Great tip.. thanks a lot
I have 21 years of experience working as data entry assistant. I constantly read several blogs to keep myself up-to-date with the advances in data entry profession. I really enjoyed this blog post. From my several years of experience, I agree with you 100% when you say, “ We all know that data validation is a very useful feature in Excel. You can use data validation to create a drop-down list in a cell and limit the values user can enter. ”
Keep blogging. I will come here again.

Hi,
This is really very helpful.
Thank you
how can i assign two validation on a single cell
one is for list validation (means the data should be from that range)
second i want to prevent them from repetition
how can i do this ?
P7 to P506 have GR# which are for list
i want to prevent C column to not to repeat and should be from the P column

YOUR COUNTIF FORMULA IS REALLY HELPFUL AND WORKS. I TRIED SEVERAL SITES BUT THEIR FORMULA DOES NOT WORK. ONLY YOU HAVE GIVEN A RIGHT FORMULA!
THANK YOU!!!!!
