Excluding Cells With Errors Or Zeroes Before Doing STDEV
Mar 15, 2013
I'd like to calculate the standard deviation and mean of a whole load of data. Unfortunately it has some errors, FALSE values, blank cells and zeroes I'd like to exclude. Calculating the average is no problem as the AVERAGEIF function works fine, but there is no equivalent for STDEV. The (array) formula
STDEV(IFERROR(E29:E32,FALSE))
ignores the cells with errors and calculates the SD, and the (array) formula
STDEV(IF(E29:E32>0,E29:E32,FALSE))
ignores the cells with a value of 0 in them and calculates SD.
How can I combine the two into one formula?

I am having trouble figuring out a way to get around this situation:
I have a to find the minimum in a range. I have used =Min(range)
However, i wish to exclude 0 values and n/a errors in the case no data figure in one or more cells of the range.
Could you please help me figure out a way?

I am attempting to count how many cells have different values in a table while not counting the N/A's and 0's found in the table. From what I'm finding online, I see lots of formulas set up with frequency functions, but none of them are set up to exclude anything - just find unique values. I need to count the cells with values other than 0 and N/A going across each row and not count the same value twice
Here's an example of what the table looks like (the real one is over 1,000 rows and 50 columns) with column C being where the formula needs to go. I put what I would like to have returned in the cells.
C
D
E
F
G
H
5
2
N/A
N/A
0

I have a list generator that creates a set of data in a multi-column & row dataset. I would like a formula to create a list of the alpha data points only which excludes blanks and any errors.
Example:
AADD
#N/A
BB23EEFF
#N/A
#N/A12GG
CC
Results:
AA
BB
CC
DD

I have trouble with calculating standard error with multiple criteria. Below is the formula I used:
=STDEV(IF($J$2:$J$25="A",IF($K$2:$K$25="B",IF($L$2:$L$25=1,M2:M25))))/SQRT(COUNTIFS($J$2:$J$25,"A",$K$2:$K$25,"B",$L$2:$L$25,1,M2:M25,""))
The problem is the blank cells in the range that I am calculating (M2:M25). Everything is alright if there were no blank cells in M2:M25. If there were any blank cells, however, the STDEV was wrong (the countifs part was correct). It treated the blank cells as zero.

I currently have a column with each cell containing alphanumeric data of a filename.
The majority of cell data looks something like this.
"AB_XYZ_0408_00700.doc"
"AB_XYZ_0408_00708.doc"
"AB_XYZ_0408_02200.doc" etc
**Note the numbers "00700" are always 5 digits long also note the extension is always ".doc" (4 characters long). However the other parts, AB_XYZ etc vary in length based on the worksheet.
I need to ADD or Subtract "+1" or "-1" from the 5 digit number for example make "00700, into 00701"
I currently tried to separate the data into columns which provides me with the number 00700 isolated in its own cell and then I simply add or subtract 1. In that isolated cell I am able to add "leading zeroes" and it works great.
The Problem is that when I combine the separated cell data "=A1&B &C1" with the New number (in this case 00701") the problem that I run into is the leading zeroes do not follow over to the combined cell and I am left with a final filename like this "AB_XYZ_0408_701.doc" - That is missing the leading zeroes.
Also if you have a more advanced formula that could simply add and subtract "1" from the 5 digit number that would be ideal.

What I want to do is Average out a range of cells "F4:F343". That's the easy part =average(F4:F343). However I want to exclude any numbers for that average if data in coloumn "Q" = "FMC"
Would that look anything like:
=average(F4:F343)/countif(Q4:Q343, "<>FMC")
I'm also displaying it as minutes in a day so i added *24*60 to the end of the formula and formatted to Number/.00. I've entered the formula and it will calculate but when i enter FMC to the appropriate area the average wont change.

Is it possible to inset a bank into a cell, and use that cell in a subsequent addition formula?
For example;
A1 contains 1
B1 contains 2
C1 contains =IF(A1=1,"",3)
D1 contains =A1+B1+C1
In the above case the cell D1 contains #VALUE and not 3, whereas if C1 were actually blank D1 would contain 3.
The reason I ask is that a blank is not the same value mathematically as 0. The latter is the number zero, whereas the former is the lack of any number.

I have a worksheet with a data base type list (16 cols, 10000 rows deep) which contains only 30 records, for testing purposes. Each cell is bordered in all 4 sides.
There will be a bunch or reports associated with this, requiring filtering and/or sorting. The macro instructions I applied so far are:
1) Locate last row.
2) Select the range from first to last row and apply a common row height (say, 24).
3) Sort as required
4) Filter as required.
5) Print
The sorting step has invariably failed.
The funny thing is that the code I used is the one produced by recording the steps. I am able to sort that segment manually, but the macro instructions fail.
here is the code...
Selection.Sort Key1:=Range("F5"), Order1:=xlAscending, Key2:=Range("H5") _
, Order2:=xlAscending, Header:=xlGuess, OrderCustom:=1, MatchCase:= _
False, Orientation:=xlTopToBottom, DataOption1:=xlSortNormal, DataOption2 _
:=xlSortNormal

i have a column C with thousands of data. in that column, i had done a vlookup formula based on the lookup_value on its right, that is column B. some of the values arent available in the mapping table, causing the #N/A error.
i want to be able to delete those #N/A errors so that my dataset looks 'cleaner'. its tiring for me to go through each row one by one and delete them manually. i wnat to create a macro but im not so sure how to start.
in pseudo-code, it shud be something like this:
delete cell if cell_value = #N/A error.

I have three columns that i've called 'active period' and 'Date/time' and 'value'
The the value of the cells in the 'active period' column depend on the value and time.
I want to create a cell that; when i can enter a date, this date will be excluded from the 'active period' column

I'm using the following formula to calculate the % relative standard deviation of 5 values:
ROUND((STDEV(C8:C12)/AVERAGE(C8:C12)*100),6)
where C8 through C12 are all 3.48.
I was surprised to see the result of 0.000002, and not 0.000000. This formula seems to be accurate to 6 decimal places when using 5 values that are not all the same. When they are the same, I get this small discrepancy in the 6th decimal place. I attempted to troubleshoot by inspecting C8 through C12. The values were typed in as seen above (3.48) and the cell formatting is set to 2 decimals in each of these cells, so the cells themselves shouldn't be contributing to the issue.

I have a worksheet containing data in columns. For each column, I would like to calculate the standard deviation of the mid-95% of the values i.e. 2.5th percentile to 97.5th percentile (to reduce the effect of "outliers").
So first of all I calculate the values of the 2.5th and 97.5th percentiles:
A102 (2.5th percentile) = PERCENTILE(A1:A100,0.025)
A103 (97.5th percentile) = PERCENTILE(A1:A100,0.975)
Then using an array formula shamelessly plagiarized from this very website, I calculate the standard deviation of the values that lie in that range:
{=STDEV(IF((A1:A100>=A102)*(A1:A100

I need to Average the cells I7, I9, F12:F18, M12:M18 in Cell G2
Cell F12 is an Average of its respective cells bellow. (and so forth)
NRT will = 1
N/O will = 0
I have cells F12:F18, M12:M18 indicate NRT in the cells when selected I would like N/O to also be displayed however it comes across as 0.
How do I avoid the #DVI/0! Errors and get the averages to calculate appropriately.

If I have 50 data points sorted in order (oldest --> newest), how do I do a stdev function that will only pull the 24 most recent points?
Essentially, I have 14 columns with 50 data points each. At the end of the list (or maybe beginning - under the column header) I want to do a stdev calculation referring to the most recent 24 points and a second for the most recent 36 points.

I need to calculate ratings 1-5 of questions on client surveys received.
I have recurring sets of data, A1:E1, a number 1-5 is to be entered into one of the cells within this range. This same pattern is repeated 25 times....G1:L1, etc. At the end I need to total all the 1s, 2s, 3s, etc. Then I need to calculate an overall pct for each question based on the totals for that question, divided by the maximum score (5) multiplied by the total surveys received. The problem I am having is that my formula below is counting empty cells, and not giving me a proper pct.
=SUMIF(A1:E1,">0")/(5*$B$1)

I have tried a number of different ones from my search of this forum but I'm getting an error. here is a sample of my spreadsheet.
I want it to give me the lowest number, I don't want it to look at the 0's or if the cell is blank.
Here is my formula and my error:
=SMALL(N196:N203,COUNTIF($N$196:$N$203,0)+1)
my error is #num!
I've also tried others including using the MIN function but either 0 is entered or the error above.

conditional formatting. I am using the code below to conditional format every Odd row with a background/border.
=MOD(ROW(),2)=1
I would like to know how to modify this, so that it only applies the format if the cell in column A on that specific row contain data and doesn't format blank cells.

I am currently working on a football spreadsheet ranking players based on their fitness performance scores. For example, there are 14 persons on Offensive Line. I need all their test scores ranked out of 14. However, if there is a blank, I still need the test scores to be ranked out of 14.
As of right now, I have cheated, and inputted a random number to bypass the blank:
=IF($G12>10, 0,RANK($G12, $G$12:$G$25,0))
But, this now affects my average of the fitness testing scores for that position. This could be avoided if I could find a way around my first problem.

I am applying the sum function to a range of cells in a column. I've Auto Filtered my sheet to only include the data I need. Unfortunately, the sum function is adding everything in that column, even data from the 'hidden' cells that I've filtered out. I need to know what condition or parameter to apply to the sum function (or any other function for that matter), that will only add the data shown on my screen. Not the data that is hidden.

First I will post the data:

PARTIATIS106SPICE107TAN108TORRES. Jr109VAN STEEN110ACCIARITO111112113114115116117118119120
In this data, as you can see there are a lot of cells/rows that are empty. I have a macro that will copy the cells F98:F120 to F99:F121 and then copy F121 to F98, and finally delete the value from F121. In this case, it will give me a blank cell at the top and the data hasn't rotated really. All the names will be in same position.
But I DON'T want that. I want the macro to look for the last cell/row with a valid value in it and rotate the cells so that I end up having ACCIARITO at the top and everybody else to move down one row.

I have the following formula which works perfectly unless one of the cells has a value of zero;
=MIN(SUM(AD13),MIN(SUM(AK13)))
When AD13 = £60.00 and AK13 = £94.00 (or vice versa) the formula returns £60.00, which is correct. BUT when AK13 = £0.00 obviously the formula returns £0.00, but I would like the formula to still return £60.00.
How this can be done?
