So who is up for an Excel challenge?
Shelly, who is an HR Manager sent this distress call last week,
First off, I LOVE your site. It is the first place I go for any excel question and I love the daily emails. I’m not sure if you answer direct emails, but I’m begging you to at least read this and let me know if I’m crazy or not (good thing you don’t know me personally :>). I’ve searched through you ‘ask an excel’ blog and I have not come close to anything I’m trying to accomplish. I’ll do my best to explain it.
I have a group of employees- lets say 100 employees.
Each employee has a performance rating attached to them.
I want to divide the group by 5%, 15%, 65%, 10%, 5% based on their performance rating.So for example how I manually do this is by running the report of employees.
I then sort the list by Performance ratings from High to Low (0.0-5.0 is our range and you can have decimals in between 0.1, 2.5, 2.3 etc.)
I then take the total number of employees and calculate the top 5%, next the 15%, then 65%, then 10%, 5% (so breaking them up into groups).
Doing this isn’t horrible, but I have to do this for each department and we are talking 700 departments. Each department is not alike- so some may have 50 employees while others may have 200+.
Is there an easier way to do this in excel??
Anytime an email starts with I Love, I am all ears. So naturally I read the entire mail. And I had to sympathize with her. 700 DEPARTMENTS?!? Can you imagine dealing with 700 departments with lots of disgruntled employees. I remember my performance evaluation & rating days back when I had a full time job. Almost everyone I knew hated their bosses during the appraisal season. And when hikes are announced, everyone (including the person with fabulous hike) would call their favorite head hunter and flirt. Aah, good old days of ratings & reviews.
But I digress.
So going back to our HR manager in distress, how would you help her?
Your challenge – highlight employees by performance rating
Here is your challenge.
- Download this file.
- It contains data & coloring rules.
- Set up conditional formatting such that you can highlight the data based on the rules
- Bonus points if you can set up conditional formatting rules such that they work on any sheet (assuming each department has their own sheet of data in same format)
- Share your rules & solution with us in comments
- Feel jolly good knowing that you are awesome in Excel.

Conditional formatting is one of my favorite features in Excel. Naturally, I want you to be awesome in it. Check out these tutorials & examples to understand how to solve this problem.

Now, some of you might be in same boat as Shelly. Please note that I sympathize with anyone who deals with people from 700 departments or more. But sympathy seldom solves struggle. So, go ahead and download my solution. Break it apart, examine the conditional formatting rules and fire the bottom 5% of your employees. Well, go easy on the last part 😛

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!

Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
