Help with Formula

[AccessHelp]

Hello all,

I have an Excel sheet with state and county data. Column C indicates which
state and Column D indicates which county in that state from Column D.

I want to write a formula for percentile (Percentile()) and standard
deviation (STDEVP()) to determine percentile and standard deviation for any
state or county that I choose. Since there are more than one state and one
county in the sheet, I don't know how to write those formula.

In Excel, there are formula like sumif() and countif() if I want to sum a
specific state or county or count the records of specific state or county. I
do not find similar formula to do the percentile and standard deviation.

Please help.

Thanks.

You can use a formula like
=VAR(IF(C1:C20="CA",D120,""))

Remember to use CTRL-SHIFT-ENTER after typing the formula...

Hi Sheeloo,

Thanks for the formula. I tried it, and I got the #Value! error. Just
curious, if it works, is it going to turn out the way percentile and stdevp?

Thanks.

Did you use CTRL-SHIFT-ENTER?
If you just press ENTER it won't work...
Also I gave you Variance formula showing how you can use condition to
restrict the values passed to it...
You still need to use PERCENTILE or STDEVP instead of VAR...

Good morning Sheeloo,

You are right. I forgot to do the CTRL-SHIFT-ENTER. No wonder it didn't
work. Now it works on percentile and standard deviation.

You are the best! I have definiately clicked Yes on the rating.

Thanks for your helps!
