Floating Range For Excel Functions - Calculating Stdev And Average
Jan 22, 2014
I 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 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?
What could be the syntax (in a code) for averaging a range in col C. the range values are given in E3 and E5. (E3=508 & E5=1200) These values changes each time I open the workbook.
Excel function or macros for calculating the average of waterSD column where the TT column is less than or equal to 100(red markings). functions like IF TT IS LESS THAN OR EQUAL TO 100, THEN CALCULATE AVERAGE OF WATERSD....
I had done manually on the right side in the attached excel sheet. only those yellow markings.
Because already I have some macro which do this process but it is not accounting for the TT column less than 100. it starts from 200 TT values. but i need to include 100 TT also. That's is where now we have yellow markings. I will provide you the macro code if you can edit that where it will start calculating form 100TT value, it will be really great. The code is,
[Code] .....

I'm trying to calculate the average for a range that begins with cell B15 and has various end points, depending on the day (since I'm pulling 2 actual years of data that strips weekends and holidays, as opposed to going back a set amount of days/years). Syntax for cell B4 to reflect the average of range B15 to LastRow? I tried several things and it didn't work. Rows 1-12 are being reserved for the summary calculations that will then be pulled into the final Dashboard.
In our sql server table, we have a field of type DATETIME. This field is populated by a vendor product with the elapsed time of an event.
We created a SQL Server view of this column and other columns of info joined together from several tables.
Then we create in Excel 2010 a new spreadsheet with a data connection to the SQL Server, instance, and view that we created.
Excel 2010 displays each of the columns in our view.
The elapsed time column appears as "dd hh:mm:ss". However, when we click on a cell to look at its formatting, Excel lists it as general.
We want to calculate the average time in this column.
We go down below the data, click on a cell, and insert =Average(C2:C17215) and we get an error saying dividing by zero.
We have 17,000+ rows of data, so there is no divide by zero math going on here. Each row in this column has data, so there are no blank cells.
We have spent some time web searching. We then tried various methods of calculating this. Nothing has worked. In most cases, we get the divide by zero. We tried some solutions that mention using an array forumula, but that just changed the error to an invalid value error.
In column A I have a list of 5 Auditors labelled Q1 - Q5, 5 Coolum’s across in column F I enter in their scores as a % e.g. 80%. ...So Q1 - 50%, Q2 - 60%. In column A37-A41 I have Q1-Q5 listed, in Column B37-B41 I need to calculate the average deviation per Auditor eg. If Q1 has 2 entries of 50% and 75% return average value in cell A37 which should be 62.50%. I am trying to calculate the average for each Auditor. find attached example.
Is there a way to put a floating date range in the criteria much the same as can be done in excel ie greater than Today() but less than Today()+3? I don't want to keep going in and adjusting the query if I don't have to and if I don't keep the range tight there is too much data.
the scenario is a spreadsheet for adding call centre operators evaluations (1 being worst and 5 being best) from the clients. in the spreadsheet, i need to create a function to add a quick evaluation based on the operators score from the client
so if the score is 4 or higher it would read "good - improving"
and if it is less than 4 "poor - improving"
i think this is just a simple IF question...but i have forgotten how to do it
I'm trying to calculate a monthly average from a set of daily values in a separate sheet. I managed to use some nifty code to return the address of the first value in the month, and the address of the last value in the month.
I tried to create an AVERAGE formula to compute the average between these two looked up address and I'm getting various errors, including #DIV/0 which doesn't make sense to me. Here is the summary of the code I'm using, in generic terms.
Formula to lookup first address in month: =ADDRESS(MATCH(A57,'Sheet2'!$A$1:$A$2000,0),12,1,TRUE,"Sheet2")
Formula to lookup last address in month: =ADDRESS(MATCH( DATE(YEAR(A57),MONTH(A57)+1,0),'Sheet2'!$A$1:$A$2000,0),12,4,TRUE,"Sheet2"))
A57 is the cell in Sheet1 containing the relevant month, for example in this case it is 4/1/2008 (displayed as Apr-2008). Column A in Sheet2 contains the daily dates. Column 12 in Sheet2 contains the relevant data that I want to average.
I've tested the two address lookup formulas and they are working fine. I assume I'm missing some sort of small conversion such that the average formula is not reading the ADDRESS formulas as addresses.
I have a worksheet which has various figures for each day of the week however I need to establish the weekly average of these figures.
Due to the way in which the figures are displayed, I am unsure how to use a formula which does not require a range with cells located adjacent to one another.
I have attached a test sheet as an example. The cells in yellow require the formula and I need a weekly average for criteria 1-3. This formula also needs to be compatible in Excel 2003
I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below: ... C9 39.65 653.95 5.28 163.56 99.56 14.49 ... ... E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ... G9 111568 298021 12940 31645 181797 36996 ... .... ...
I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?
Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly
I have a spreadsheet that we are using as a Skills Matrix for the team. The area that the team member deals with is listed in Row 3. The scores for each person are recorded in Columns D to M. The process steps being scored against are in Rows 8 to 38, and are seperated by the area of responsibility.
I am trying to work out the average scores of each person depending on their area of responsibility. I can work out the totals easily enough using:
This is becuase it adds the 2 averages instead of working out the total average score. Is there an easy way around this?
i.e. For team members who have CM in Row 3 I need an average of certain cells, for team members who have V in Row 3 I need a different average and for those team members with both CM and V I need an overall average.
I have a database with monthly tabs and a summary sheet, on the summary sheet I calculate an average length of stay for each month (tab) but I need to find the yearly average and I don't know if there is a formula that would calculate the true average by using the monthly averages.
I have a table with 9 columns filled by a letter (A, A-, B+, etc). This letters correspond to grades (4, 3.67, 3.33, etc). The tenth column is supposed to contain the numerical average of all 9 letters in the line.
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 have a set of % score values (e.g. 88%, 94%, 82%, 67%)
I would like to know if there is a relatively simple formula that can be used to calculate the AVERAGE DEVIATION from 100%, as opposed to the AVERAGE DEVIATION from the mean, which is what the excel function =AVEDEV will return.
E.g. The Average Deviation from the mean for the the above set of values is 8.25%, whereas the Average Deviation from 100% is 17.25%
I can create a complex manual formula which sums absolute values of the variation from 100% of each score, and then divides by the count total of the number of scores, however this is flawed for several reasons, including the fact it is very time consuming when used across a large set of scores, and it is corrupted when a non score exists in a cell (some of the 'scores' may be '-', in which case they should be ignored and not included in the calculation of the average deviation from 100% by treating as a 0% score (and a deviation of 100% from 100%).
I am having trouble creating a formula that would calculate the weighted average cost depending on the type (i.e. weighted average cost of $28.84 for A, weighted avg cost of $70 for C).
I am trying to calculate the average Talk Time into Minutes and Seconds. Every time I have tried, I get the wrong average.
For example, if I have a total of 53 calls and the total talk time is 4:19:05, what would the average talk per call be? I tried doing everything in seconds (this would give me a total of 15545 seconds) but the total I was getting is 4:89.
What would the formula be to get the correct average time?
I have a series of numbers in the column AB56 going downwards and in AC56 going downwards their respective counts in a data-set.
What I would like to do is find the average of the min and max, the min and max for the average calculation are both determined by looking at the count column, isolating the max, isolating the min, provided they both have a count greater than zero then averaging both results.
In this calculation the MAX is 0.155326043 because it has a count greater than zero, the MIN would be 0.138120697 as it has a count greater than zero, the average of both would simply be 0.1467. i.e. Average(0.155326043,0.138120697)
i have data on excel which has the following fields:
Invoice No,Inv.Date,Month,Customer,Part Number,Description,Qty.I want my final pivot table to have the following results for every part no. and description
Total monthly sales
total year sales
and for each model sale calculated as sale quantity / week
I have tried the following way but it did not work:
just next to the pivot table under the heading"AVG" i used the following formula to get the sale/week on cell o6=grand total sale /(applicable no. of weeks).and when i am copying the formula to the cells lying below the formula is being applied as that of the first cell so getting the same result for all the rows.is there a way to calculate sale/ wk within the same table
