Standard Deviation Formula That Will Ignore 0 ,,,,, Help...

hi guys,

i have a simple spreadsheet where i'm totalling a few values thru a formula. it's similar to this:

=D13*F13

i'm trying to create a funcion that says if d13 * f13 >= 300, i want the value to stay at 300 max and at the same time, if d13 * f13 < 300, i want the total to remain whatever it is.

i have been able to create both of these formulas successfully by themselves but i can't combine them. is this possible?

any help would be greatly appreciated!!

I want to add data points to the scatter plot that are not part of the data
ie. add points to find their concentration on a standard curve.

I have a formula in cell C1 (=A1/B1). I want to copy this formula down to row C20, however rows A2 to A20 are empty so C2 to C20 show (#DIVO!). Is there something I can put in the formula to make column C be blank until the data is enter into Columns A & B?

Hi,

Im working with a large data spreadsheet that has Yes and No answers in different columns. There are blanks within the selection too.
I need to calculate only the Yes.
I have tried using the filters in the Pivot Table field list and they are not working.
So now i'm trying to add a COUNTIF formula in the Calculated Fields section.
The formula I'm using is =Countif('Time limit extension'="yes") and i get the answer "too few."
What should I be using in the formula to get the calculated field to work? I have search the whole forum and I haven't found an answer that can help me.

Please HELP!!!

Hi there

I am trying to calculate our On Time Delivery. I want this as a simple percentage of jobs. I have got this running in the following way:

Column M - Estimated Delivery dates
Column N - Actual Delivery dates
Column O - =IF(SUM(M2-N2)>0,1,0)

Then I have calculated On Time Delivery as: =SUM((SUM(O2:O252))/(COUNTA(N2:N252)))

This seems to work fine. My problem is, if we enter a date in Estimated without a corresponding Actual date, the formula for Column O fills out anyway and improves our On Time Delivery Percentage. How can I set this up so that the formula doesn't calculate if there is no data in Column N?

Any help much appreciated

Thanks,

I have an excel worksheet that adds two other worksheets in a data
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.

The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.

I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.

Any ideas?

Thanks.

I need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details

I have a spreadsheet that when I copy the formula, it copies correctly
(changes the cells it should subtract), however, the result stays the same.
It matches the formula I copied it from, even though the cells to calculate
are now different. I even did a paste special and said only formula, but
still, same result. If I actually type in the formula, it works fine, but I
have a lot I need to copy and paste. Is there a way I can fix this?

Thanks,

Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin

Hi Everyone,
I have searched online and in help but can't seem to find the best solution...

I have values like 00904BB303D6 that need to become: 00:90:4B:B3:03:D6 (the value is always 12 digits, and the : needs to appear every two digits.) Is there a formula that can easily do this for me? Your suggestions are greatly appreciated!

Thanks in advance!!!!

I have a spreadsheet with simple (addition/subtraction) formulas. The file is quite large and the formulas are too. All of a sudden, the formulas stopped working except when I double click in the cell containing the actual formula. For example, if I enter "2" in each cell, A2 and B2, cell B3 should reflect "4" because there is a formula in cell B3 which totals cells A2 and B2. Only by double clicking on cell B3 will the program actually calculate. I'm totally perplexed and so is my IT contact. Anyone?

This formula is supposed to calculate difference between today and date hired to give years and months of service. Works fine for all except if the person was hired in year 2000 then this formula shows 110 y. Any one know how to fix this? or have a different formula that works.

=DATEDIF(E21,TODAY(),"y")&" y "&DATEDIF(E21,TODAY(),"ym")&" m"

Thanks

Hi Guys,
I need help....I am working production scheduling with Start and End time but there is a lunch time and tea time. Is there any formula to calculate Start time to End time with excluding lunch time?
Here is example :

Lunch time :12:00pm to 1:00pm.
Duration Process :6 hours.
Start Time (8:00am)
End time (5:00 pm)

I need a formula to calculate from Start Time 8:00am and what is the End Time? with 1 hour lunch time...

Thanks,

From limited experience I know that excel calculates dates via serial numbers.

I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)

I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.

What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?

Hopefully a simpler question for your experience level than mine.

I need a formula to calculate overtime, after a work week of 40 hours.

for example: if an employee works 10 hours a day we would not count towards overtime until the employee completes a 40 hour work week.

Any suggestions would be greatly appreciated!!!!!

Thanks,
