Calculating Stdev When Values Include #n/a
Sep 14, 2009I have a set of values. #N/A413636363632. The #n/a is there on purpose for charting reasons. How do I calculate the stdev of that range? i.e. ignoring the error?

View 2 RepliesI need to calculate a Stdev and Average based on a specific range. However, my range is not constant in the time. For instance, today I may need to calculate these functions based on 30 numbers, but tomorrow on 25 or 15 or 50...
Is there a way to automate this process by changing the number of data points to include in the range in one single cell and avoid manually adjusting the range in accordance with needed data points?
In other words, I would like to change the value, let's say in Cell A1 from 30 to 50 and then Excel would re-calculate the StDev and Average based on 50 data points and not 30. Is that possible?
I need the values that are copied from the template to copy over in text form from the "Data" Tab. Secondly, the master sheet has multiple lines for each vendor. For the area highlighted in red I'd like for it to copy all cells in column C for the vendor and search the vendor by name. Then, move to the next sheet.

10.56 m2
14.23 m2
21.34 m2
How do i calculate the total of these amounts?
Is there a formular to remove the "m2"?
I have tried using =SUBSTITUTE(A1,"m2","") which deletes the "m2" from the cell, but then I can't use =SUM(A1:A3) as this totals the 3 cells as 0.
If i use =SUM(A1+A2+A3) the total is correct, but I have over 3000 cells in one column to add together.
Is there a formula or something to remove all instances of "m2" or "m3" from the whole sheet or another way i can calculate the totals.
I want to be able to look up and match several values in my worksheet to confirm, that an entry is valid. I would like the test to return an OK / NOT_OK value at the end of each entry. In the attached file you will find four different variables. In order to include an entry, it must be matched to find related entries, before it can be included.
For an entry to be OK, it must contain a company that has been listed in the same industry, in four different quarters (not necessarily in the same year). A company can be listed in several industries, but as long as there are not four entries in the same industry in four different quarters, the entries are not yet OK (hence NOT_OK). Therefore the only entries that are valid in the attached file are:
Company A Q1 2009 Administration OK
Company A Q2 2009 Administration OK
Company A Q3 2009 Administration OK
Company A Q4 2009 Administration OK

I'm calculating a variance for a set of actual numbers vs. variance numbers. When there are no actuals, I don't want the formula to calculate a variance. How can I do this?

I'm looking at the formula in Sheet3, cell F5. You'll see that the criteria "--(Sheet2!I:I<>Sheet1!O:O)" does not seem to be working. I need the formula to not include any values from Sheet2!E:E, where the corresponding value in column I does not equal any value in Sheet1!O:O. Also, these values can change by user so its not as simple as just typing them in to the formula as an array...
That VBA part of this is that it's in a macro, so if there is any way to make this easier using code instead of a simple formula.
I am looking to build a VBA to do the following action:
Look up an ID number from column F (ID numbers are separated by an empty row at current),
then check whether there is a corresponding value in columns N to P,
if there are values, copy them onto a different sheet into three different columns
if there values below this particular row, i.e. if the rows below say row 9 (where we looked up the ID number) in columns N - P are not empty, also copy all these values and add additional rows as needed on the sheet this is copied to
then look up the next ID in column F and do the same until there are no more IDs
I have a pie chart on a pre-defined table with 15 categories where the data will populate over time (presently only 3 are populated) in descending order. As some categories will be blank/zero for a while, I'm trying to find a way to avoid showing the blanks/zeros on the pie chart. As I am trying to display the legend on the pie chart segment, any zeros cause the remaining labels to appear grouped together and rather messy. I would therefore like to hide the zero data from the pie chart so the labels do not appear, or to automatically extend the range to only include all non-zero values.
I found the following formula which, when used as a named range, automatically extends a list for data validation:

I don't know whether there's a similar formula or whether a few lines of VBA are required to run whenever the chart or data worksheet are selected..?
I need an autofilter which filters rows based on a list of values (+50).
The problem is that I am looking for rows INCLUDING values from the list, not for exact match.
I am not able to make excel filter values including the values from the list... I am able just to filter values matching exactly values from the list.

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
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'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 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 have a list of numbers and i want to calculate avg and stdev but i do not want "zeros" or "blanks" to enter into the calculations. I have a formula for avg but i need one for stdev.

View 12 Replies View RelatedI have a large spreadsheet with about 250 worksheets, each of which contains among other things a row of values that require further calculation (the values are being entered manually). The format of these rows is simple:
CodeH343B734G232L383N343M386
Count 1 3 2 4 3 2
Given that these rows are identical in size and they are in exactly the same cell positions in each of the 250 sheets, I need to find a way of getting each of the values entered in each of the 250 sheets automatically copied across to a different sheet and added to an existing total. In my limited understanding of Excel I consider such operation to be similar to a sum function which involves multiple cells in multiple sheets. Despite my best efforts I’ve yet to find a solution to what may be a very simple problem.
I have a spread sheet which is organised in date order column A and produces three signals Buy, Sell, No trade in column S. If i get a signal to buy or sell the price is taken in column T so i might have Buy - 1.9977. I wish to calculate the diff between the value taken to buy in this eg and deduct this value from the opp signal at some point ie a sell signal. Other buy signals and notrade signals should be ignored. The opposite is true for a sell signal
Eg
A,s,t,u
13/4/07, buy,19955,35
12/4/07,no signal
11/4/07,no signal
10/4/07,no signal
9/4/07, no signal
8/4/07, no signal
7/4/07, sell, 19990,13
6/4/07,no signal
5/4/07,no signal
4/4/07,buy,19977
if a buy signal is generated then in this eg 19990-19977 gives the diff if selling then 19990-19955 gives the diff .
I created a pivot table in which sales amounts are represented and a derived table in which market share percentages are showed. Now i am looking for a formula that is able to calculate average market share values. Depending on which country i selected in the pivot table and which category, the number of active companies are changed. How can i formulate this formula to calculate average market share percentages in a certain period. check out my attached file to clarify the situation.

I'm trying to calculate total occurrences of a given month. I have included the spreadsheet for reference with totals.
I only want to calculate when the Policy column has a "N". If it has a "Y" I do not need to do anything
If the Policy has a "N" I want the formula to look at the V and P columns and give me a total in the Total Occurrence column. I want it to look at the entire month for a grand total.
If the V or P column has a 4 or less it should equal 0.5, if it has a value is between 4 and 10 it would equal 1. So in the Total Occurrence column should calculate the all of the 0.5 and 1's based on each set of columns and give a total. In the example that I have given in the spreadsheet the total in the Total Occurrence column would be 2 because Jan. 1 has a N and a 8 which equals 1 and Jan. 3 has a N and a 4 which equals 0.5 and Jan. 5 has a N and a 4 which equals 0.5 for a total of 2 occurrences.

Here's the formula I used: =IF('End of Month'!L3>=0,('End of Month'!L3-'End of Month'!N3),IF('End of Month'!L3>0,('End of Month'!L3-'End of Month'!M3),(0)))
Should return value 339.
The formula should simply take the current month value and subtract it from the previous month value BUT if the value is zero, then it should go to the prior month and so on until it retrieves a positive value.
I've also tried to following formula without any success:
=IF('End of Month'!H3=0,('End of Month'!H3-'End of Month'!J3),
IF('End of Month'!H3=0,('End of Month'!H3-'End of Month'!K3),
IF('End of Month'!H3=0,('End of Month'!H3-'End of Month'!L3),
IF('End of Month'!H3=0,('End of Month'!H3-'End of Month'!M3),
IF('End of Month'!H3=0,('End of Month'!N3-'End of Month'!O3),
IF('End of Month'!H3>0,('End of Month'!H3-'End of Month'!I3),(0)))))))
This pivot table is used to track referrals for an employment service, and needs to show monthly totals of referrals, enrolments, cancellations and placements.
I have the referral date as one of the row lables, but it seems that each of the others now only reflectes back to that date rather than the date entered in that value
EG:
5 clients referred in September, One was placed in October, 2 in December and 1 in Jan but the totals for placed are all showing in September rather than the month the clinet was placed.
What I have is a spreadsheet with a whole bunch of sporting data on it. see attachment for an idea of the layout, Stats.jpg
In these data each round a player is given a rating. What I want to do is calculate is the average rating for each player across the last 3 and 5 games they have played. When a player misses a game they get a rating of 0 for the round. I want 0 ratings to be ignored in the running averages. Additionally, games yet to be played have a 0 in the cell and should be ignored. To get overall averages ignoring 0's was simple I used the averageif function, but I couldn't figure out how to use that but only extract the last 3 non 0 values. I currently have data up to round 12, so if a player has played in 12, 11 and 10 then the 3 round average should just be the average of these 3, but if they missed for example round 11 then the 3 round average should return the average of 9, 10 and 12.
The data is set out in the following way.
In column B I have a list of player names from cells B3:B618.
Across row 1 from N1:AM1 are labels "round 1" "round 2" etc.
The ratings for each player in each round are in N-AM and from 3-618. i.e. N3:AM3 contains the weekly rating for player 1, 4 contains player 2 etc.
I would like the 3 round averages to be returned for each player in column L and 5 round averages in column M.
I am currently using a pivot to return and populate the required data but this does not refresh correctly and returns zero values every time this report is refreshed. I am therefore hoping that there is a way to calculate this using formulas .
The following applies:
The attached document has 2 tabs: Date AND Report
The Data tab feeds the report tab
The REPORT tab has 2 reports in it but doing the first one then I should be able to do the second one. If you look at the first table you will see the data that needs to be populated. I have added a highlighted (in YELLOW) row at the bottom of this table which shows you which columns populate what column
Requirement:
I am after something that will populate this table in a descending order - IE: the figures in the DATA tab Column BE should be sorted from highest to lowest. It must be filtered to the top 30 results only and then all the other columns must be populated.
Column H in the REPORT tab should be formatted to [h]:mm
Column F & G in the REPORT tab should be formatted to dd/mm/yyyy hh:mm
If I have a list of 6 values and a number that I want to get as near to as possible (above or below) using any, and as many as needed, of these 6 values - is there a way of calculating the nearest value? And, if there is, is there also a way of showing which values would be used?
Example:
Value 1 = 0.190
Value 2 = 0.278
Value 3 = 0.593
Value 4 = 1.079
Value 5 = 2.075
Value 6 = 2.998
Value I want to get as near to as possible = 3.644

If the given date is 15 Sept 08, I need all values in Sept - Mar to be totalled.
