Weighted Standard Deviation

I have a spreadsheet where I need to calculate the increase in % one year over the other in column D for Eg if Profits are 95415 in Jan 2008 (Column B) and 80215 in Jan 2008 (Column C), then the % Increase will be (95415-80215)/80215 *100

I can calculate the formula for this , but the problem comes where for eg there is a loss in Jan 2008 for -95415 and there was a profit in Jan 2007 for 80215. How do I set up formula to take negatives & positives into account in calculating the increase or decrease/

Your assistance or anybody's on the forum will be greatly appreciated

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

Entering time values in custom format [h]:mm:ss
Cells accept hours over 23,
Adding cells in column returns correct total time.
Have not found a way to multiply these cells by a $ hourly rate.
So use HOUR(cell ref) and MINUTE(cell ref) to capture values in referenced
cell - then use these values to calculate total payment for $rate per hour.
However, the HOUR(cell ref) formula returns the hours in excess of 24 when
the cell contains an hour value in excess of 23 (ie 27 hours returns 3).

I'm trying to come up with a solution to calculate the man hours and days worked over multiple sheets.

I have a file that has 8 sheets. the first seven sheets are the days of the week and the 8th sheet is where I want to calculate the hours.

The days of the week consists of "Name" "Date" Hours"

The 8th sheet consists of "Name", "Days of the week in their own column (7 columns in total)", "Total Hours" and "Total Days Worked"

Now... each day is always a different group and what I'm hoping for is to create a formula that can grab each name with their hours and throw them into the 8th sheet. So when the end of the week is done I have all the Employees weekly hours and days worked all finished.

I hope this makes sense. This file is to track about 100 employees that are on a rotational work schedule.

I have attached a sample file.

Thanks in advance for your help.

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).

I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).

Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.

Column 1 has roughly 20 rows of information. Cell C1 has the formula =A1.

Is there a formula so that when I drag C1 horizontally into D1, E1, F1, ..., the values placed in each cell will be =A2, =A3, =A4, ...

I do not want to transpose the values from column 1 into C1, D1,.... I want these cells to have a formula that links them up to column 1's values

Thanks

Is it possible to assign values to names in a list, so that when you validate
it as a drop-down list, you can select a name from the drop-down and it's
corresponding value will be added to separate cell? Basically, I have survey
questions which have five possible responses: Excellent - Very Good - Good -
Fair - Poor. We want to assign a value to each, 5 for Excellent, 4 for Very
Good and so on, so that when a response is selected from a drop-down, it's
value appears in a separate cell (so that we can calculate a total and
average score from the selections).

Thanks

I need information on how to enter the proper syntax (formula) so that excel
can calculate overtime hours. In california over 8 hrs in one day is
overtime. The 8 would be considered regular hours and anything over is OT.

Happy Day to all,

Can you please help me,

A1= time in
B1= time out
C1= time in
D1= time out

I want to calculate the late and under time,
Office start at 9:am w/30 mins Grace period,
The break time is one hour only, please include over breaktime in calculation.
End of office hours 6:00 pm, strickly no over time

Hey

I have three columns containing last name values from 3 different sources that I've brought into one sheet. I am trying to find a way to compare all three values to establish if they are the same.

Of the three values there is no master, Each value may be different. So essentially it would be like doing =IF(a1=a2=a3,"match", "nomatch")
But of course this isn't possible.

I don't care about obtaining detail about which value matches which. I just need true or false response as to whether all three values are the same or not.

Thanks for any help anyone can provide.

Hi,

Try this...

There are some valid datas in the cells A2 (Eg. 100), B2(Eg. 200), C2 and D2.
Data validation is used in cell K2 to limit it to a set of values.

Can we implement this formula?

IF(K2="Approved")
{
A2=A3; B2=B3; C2=C3; D2=D3; K2=K3;
}
ELSE
{
no change to any values.
}

Thanks in advance...

In Excel I have been trying to find an easier way to calculate a time
difference where the times cross midnight. Example:
Start time: 23:50:00
End time: 00:15:00

How would you formulate an equation to determine the duration of time or
differnce between the start and end time?

Hi All,

If I drag a formula to the right it adapts the column letter in the formula from A to column B, which is standard Excel functionality.

However, if I drag the formula to the right I want Excel to skip a column each time.

In other words:

=A1 ; = B1 ; = C1

Should be

=A1 ; = C1 ; = E1 etc...

Is there an easy trick to do this?

Thanks,

Michiel

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!!!!

Great tip! But one thing: On my machine (Excel 2008 Mac), the values in the formula cell are not correctly calculated simply by dragging. Instead, the values are equal to the cell above (the first entry formula value). To get the correct value, I need to click in the formula bar and then hit enter. (I only discovered this after an hour of tinkering, figuring I had botched the formula!)

Are there any ways around this so that it updates upon dragging the formula?
