or .. veni vidi viblogged
well, after a brief globe trotting to few places here and there, I had to go to where literally every other Indian IT employee goes. America. After spending most of my first 4 days here indoors I guess I am both qualified and bored enough to write this post. And after spending good amount of weekend time clicking remote or flicking matrimonials or licking your plate, I am sure you are also eager to read this post while trying to focus on work. So without further ….
My travel had nothing exciting to write home about, unless you want to call watching-6-movies – getting-served-by-male-air-hostesses – and-loosing-one-of-your-suitcases-in-transit exciting. Anyways what is really the matter with muscular and cold looking male air hostesses? Have I formed stereotypes watching too much of those red skirted kingfisher ladies or it is how they work in this part of the world? well .. whatever
So I walk out of the Columbus intl. airport feeling anorexic from all the in flight consumables and hail a cab. As I try to explain the driver where I wanted to go, I quickly learned that he knows nothing except driving. I mean not even reading or writing. I guess this is what us consultants call verticalization. So while I spell letter by letter and point it on the GPS unit our man was able to configure the address and get the directions. He is a sweet man though.
The first cultural shock came in a matter of 23 seconds. I have quickly learned that I have reached US on a super extra long weekend called thanksgiving weekend. Well, I couldn’t be more thankful though. I was in no mood to work after what seemed like a zillion hours of listening to “stow your brain in the overhead compartment, buckle your belt to the seat and restore your feet from the seat in front of you”. So I spent rest of my day wondering what my wife has packed in the other suitcase that went missing in the transit. I realized it contained important life saving stuff like my camera, bathing soap, bed sheet, pillow and eatables.
Next morning my room-mate suggested that we go get some milk from the near by pharmacy. So we walked across the street and entered in to a place that looked almost like half the size of Chennai central railway station. You could buy Christmas trees, digital cameras, bedsheets apart from medicines there. I must tell you this, here everything that is in liquid form (can be liquified) is measured in gallons, including but not limited to espresso shots, coke or tequila.
Rest of my 4 days here involved more of walking across the street to buy some coffee or wearing too many clothes and watching some Simpson’s while sitting on the couch. I guess that part matches pretty much with the life in India, except that I still miss my suitcase.
A last tip to anyone curious enough to read till here: a gallon actually means 3.7 ltrs but feels like a whole lot of coffee that an entire state of Goa can drink in a morning.

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.
How to convert a figure like 870.70 into 870 but 871.70 into 880 using excel formula ? Please help.
