Standard Deviation Of Dynamic Range |
Standard Deviation Of Dynamic Range - Excel |
|
I have a dynamic range that I need to be able to calculate the standard deviation for. The dynamic range sometimes has blank cells and #N/A cells which I do not want included in the calculation. However, there are sometimes cells with the number 0 in it (instead of blank) which I do want to include. I have come up with an array formula, but the standard deviation it calculates is not correct. The formula is:
=STDEV(IF(ISNUMBER(A3:A20000)*ISNUMBER(A3:A20000),1,0))
*This is an array formula calculated by pressing CTRL+SHIFT+ ENTER
The number it calculates is 0.43, however, this is incorrect. If you just calculate the standard deviation of the actual data points in excel (cells A138:A5055 in this case) : STDEV(A138:A5055), it returns 0.17. This is the correct standard deviation. Could someone please help me with this?
Kind Regards,

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.

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?
I have the following in G2:
=VLOOKUP(A2,Sheet1!A:D,4,FALSE)
The formula returns the correct result, which in this case is a number - 2
When I fill down my range, the formula copies correctly, but every result is the same. 2.
However, if I go to the next cell down (G3) and activate it by pressing F2, and then hit Enter, the result changes and is now correct.
Any ideas whats going wrong?
Im trying to Sum the total of a number of cells using the following formula:
=SUM(F57,H57,J57,L57,P57,N57,D57,,R57,V57,T57,X57)
however some of those cells might be blanks as they are dependant on other data. The probelm im having is that when they are blank i am getting the the sum as 0. i know this isnt the case but dont know how to rectify my code.
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.

ie. add points to find their concentration on a standard curve.
(The reason I need to do this is for importing into Access, the database treats empty cells as NULL which is what I want. Blank (but not empty) cells screw the import process up.)
(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,
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
Example:
A1: 50
A2: 10
B1: 60
B2: 20
A3: Formula: =A1+A2 Displays: 60
Right click A3, Copy, right click B3, paste
A3 displays 60
When I click save, it will change the display value to 80.
I am trying this on his workstation and mine. Mine has Office 2010, so I think there might be an issue with the file itself.
Also, not just copy and paste. I can also just click the top cell after filling in the formula and then drag the bottom right of the cell downward and it will do the same of filling in the correct formula, but have the incorrect value.
I know that I could get him to just click save each time before really looking at the results, but that is just a band aid to the problem.
Any ideas how to fix this?
Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")
as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.
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 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

I have a spreadsheet with some cells setup with a drop-down list containing
Y, N or N/A
This is being used on a TabletPC but if I make a mistake or need to change
back to a blank field I have to invoke the soft keyboard, activate the cell
and hit backspace then close the soft keyboard - quite a long-winded
procedure just to change an incorrect choice!
What I would like to do is add a blank to the list so if I have to revert
back to a blank I can just use the stylus to choose a blank from the chooser
list.
How do I add the option of inputting a blank from the Data Validation List
bearing in mind I am using the Data Validation Source box for entering my
choices directly and not specifying a range of cells?
I have tried adding "" and even a space to no avail.
Although not a betting man I would wager there is a simple 'fix' for this
but things are only simple if you know how in the first instance! ;^)

How would I concatenate a large range of cells, most of which are blank, and add a comma between each cell's value?
My range is E2:Y2 (I will be filling down), but most of the cells are blank. For example, if I F2=9, I2=11 and X=25, I would like to display them as: 9,11,25.
If in the next row, G=10, K=15 and Y=27, they should look like this: 10,15,27.
Thanks in advance!

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).
But it gets even more weird. When I click on the Column C cells and then it shows the formula up top in the formula bar and if I put my cursor anywhere in the formula bar and hit Return the formula does not change however the correct value then appears in the Column C cell. It is like the act of putting the cursor in the formula activates it to work properly but until it is activated that C cell shows the value of the cell which it was dragged down from.
This is quite bizarre. Has anyone ever seen this before? I have no idea what is going on. I ran a scan for viruses and none were found. I tried it on several new/different spreadsheets but it keeps happening.
Thanks for any tips on this.
I'm working with Excel 2003 sp 3 on Windows xp.
I have been banging my head trying to jar loose the formula to calculate man days where 1 equals 8 hours. I have one that was given to me by a coworker:
=INT(Q3/8)+(((Q3/8)-(INT(Q3/8)))*0.8)
That calculates man days from total hours. I need a formula that will total man days and return the man day answer. Example:
weekending 12/25 = 16.2 which is 16 man days and 2 hours
weekending 1/1 = 24.7 which is 24 man days and 7 hours
Total = 41 man days and 1 hour
I have also been asked if there was a way for a number to be entered into a spreadsheet and automatically put in order without a macro or "pushing a button".
Any advice is greatly appreciated!
Happy New Year!
