Stdevif? |
Stdevif? - Excel |
|
So AVERAGEIF has been very nicely explained to me at, and its a incredibly useful functions.
The averages I've taken from my dataset I then want to know their standard deviation. There doesn't seem to be, though, an equivalent function for standard deviation (STDEVIF if you will).
Can anyone suggest a function or a formulaic work-around that would allow me to get standard deviations of averages taken from AVERAGEIF.
Thanks!

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
Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?
eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.
Other than creating a table and using a vlookup function, I am hoping there is a better way?

24 hour format i.e. 15:00. How can I do this?
E.g.
Manchester United 3 - 0 Arsenal
Prediction: 4 - 1
Points: 1
I've found a formula online that works for most scores; the correct score (e.g. 3 - 0), a correct win (e.g. 4 - 1), and in the case of a draw (e.g Man Utd 1 - 1 Arsenal, and the prediction 2 -2), correct draw (but not the correct score). The points are as follows: Correct draw (Prediction = result): 4 Correct win (Prediction = result): 3 Correct win, incorrect score (Winner correct, score not): 1 Correct draw, incorrect sco 1
The formula I found online for all but the correct draw is: =IF(A3&B3=C3&D3),3,IF(AND(A3=B3,C3=D3),1,IF(AND(A3>B3,C3>D3),1,IF(AND(A3<B3,C3<D3),1,0)))))
Could someone help me work out how I can write a formula to add before the above that will check the contents of four cells (the home score, away score, home prediction, away prediction), and if the number in all 4 cells are the same, allocate 4 points? I've tried using averages, but some combinations would void this. I've also used the SUM function, but the same happens, as with MULTIPLYING.
Something like =IF(A3:D3) are equal, 4,0
Below are a few examples of what I mean:
(Result) (Prediction) (Points)
A B C D E
3 - 3 3 - 3 4
2 - 1 3 - 1 1
1 - 0 1 - 0 3
3 - 3 2 - 2 1
Apologies in advance if I haven't explained this clearly enough.
Thanks

ie. add points to find their concentration on a standard curve.
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,

Im unable to put any pics up as my work pc has java disable so photobucket ect won't work but has anyone else come across this problem and how did you rectify it? A search macro perhaps?
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.
The Geomean function doesn't work because it only uses positive numbers.
Any help would be greatly appreciated.
... If the time 04:16 falls in the time range 04:00 - 04:29, than put a one (1) in the filed x...
... If the time 04:16 doesn't fall in the time range 04:00 - 04:29, than leave the x fiel empty
Any help is appreciated.
Hoping someone can help me quickly as I'm pulling my hair out and have a deadline getting too close.
Been trailing the net and this board but can't work out how to do a simple variance.
How do I work out the difference between two numbers - including negatives.
If the numbers are all positive, it's fine as it's simply a case of A - B = C which is your difference. However, that doesn't work if B is negative.
I need a formula that would give the following:
First Number / Second Number / Difference
1 / 5 / 4
1 / -5 / -6
-1 / 5 / 6
-1 / -5 / -4
-5 / -1 / 4
Hopefully there's a simple function I've been missing.
Thanks in advance, R

HELP!!!
I have 2 colombs of data.
AT the bottom of the first, I have created a drop down menu using the "data validation" feature in excel.
At the bottom of the second colomb, I have used an "IF" function that returns a result, which depends on what value is chosen from the drop down menu in colomb 1
The problem I have is that I want the TRUE result from the IF function to be another drop down menu, being the data in colomb 2.
How do you write an IF function where the TRUE result is a drop down menu??
I tried to create a drop down menu of colomb2 elsewhere in the spread sheet, and used that cells location as the TRUE value, but this didn't work either...
ANy suggestions??
increament, i.e. A1 is 2 and A2 is 4. Now I want to fill the whole column
with this increament pattern till row A20. One thing we will all do is to
left click on the fill handle and drag it down to row A20. But if the task is
to fill to row 500, the mouse draging sometime won't be easy to locate the
row. I am wondering anyone can help me to find the keyboard shortcut
equivalent to that drag fill handle action.
Thanks

So I am at work workin on this report and I need a function that will make Excel automatically insert the today's date in a cell (let's say D90) when I fill the content of another cell (for example C90) and the that will be inserted will never change. I tried to use the =TODAY( ) function but it keeps updating the date in the cell to the current date if i reopen the worksheet 2 days later. I need the cell to keep in the cell the date of the day when I filled in the content of cell C90 and do not updated it every time i open the document to the actual date.. Thanks in advance!!
The following can be used to simulate the same, and avoid having to achieve the same with VBA's IsDate function:
STEPS:
1- Format the column (ex A) as text
2- Formula to check for valid dates:
=ISERROR(DATEVALUE(A1))
----------------------------------------------------------------------
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
'this disables the save function on the XLS
MsgBox "****Save is Disabled****"
' Following line will prevent all saving
Cancel = True
' Following line will prevent the Save As Dialog box from showing
If SaveAsUI Then SaveAsUI = False
End Sub
a set of given numjbers. For example, 1, 3 and 8 would generate 138, 183,
318, 381, 813, 831 and so on...
format the text cells (name, etc) to have text entered as uppercase
automatically although the user might use title or lower case.
UPPER function cannot make cell look at itself and perform the function
