Averaging Data By Week - Automatic Calculation?
Jun 18, 2013
I need to average data following the format below by average per week by week/store combination e.g. wk 1/store A average is 6.
Week
Store
Sales
1
A
7
[Code] ..
I can easily use SUMIFS to achieve this, but I have a large amount of data between the weeks of 1-52, a dozen different stores and I will be adding to this. I don't want to have to enter new SUMIFS every time I enter a new wk/store combination. How do I get this info to automatically calculate?

I want to create a row for each of the 52 weeks in a year. I want the weeks to begin and end on thursdays. Is there a way to automate this so that I do not have to maunally enter in each week? I need to do this for 2008 and 2009.
For example
7/31/08 - 8/7/08
8/7/08 - 8/14/08
8/14/08 - 8/21/08
etc....

Attached is a sheet I use for my pubs to send me their financial information.
Unfortunately, like most staff - they become lazy and need to be kept in line, but when it comes to money, I need it all to work out exactly.
The sheet seems to almost perfect for what I need now, but for the week commencing date on the bar business sheet.
This is the master date for all the figures inputed so I need the week commencing date to always be correct from a Monday.
At the moment the formula I have in ensures that, but when I open it the following Monday to get the figures the date changes to the following Monday from when the sheet was started.
So...is there a Makro that can run that when you open the sheet for the first time it will ask for the week commencing date which will then lock that date or would it be better inserting another sheet called calendar with week numbers and do a lookup function so that a specific week number relates to a specific week commencing?

I would like a formula to calculate wages for a week. What I have so far is broken into two formulas:
Weekday Calculation
=(C3*P7)+(C4*P8)+(C5*P9)
Saturday and public hol calculation
This is at a rate of 1.5 for first 2 hours (or cell P8) and a rate of x2.0 for any remaining hours (cell P7).
This part of the formula is returning a FALSE.
=IF(C7

In attached file, I need to find a way for "y" to be automatically calculated. But for that, "y" needs to first find out which equation to use, depending upon the corresponding entry in first column.
would somebody know how to do it ?
I was trying vlookup, but couldn't.

When i have automatic calculation on, excel freezes. When i push the escape key i get focus back to excel but then it nearly immediatley loses focus again. I have to keep hitting excel to navigate anywhere with excel. By turning calculations to manual it no longer freezes. Is there a way to identify whats causing this freeze, I went through and deleted nearly all events? Why would auto calculate freeze excel if no changes are being made to a formula?

I have largish workbooks (10MB) with a variety of formulas and lookups to generate tables and charts. Calculation is ALWAYS set to Automatic, but sometimes (not always) the formulas fail to update when values are changed. Sometimes F9 will force calculation, sometimes Ctrl + Alt + F9, sometimes (especially with charts) I have to close the workbook and reopen before they will update. The workbooks contain macros but none are running when this happens. A search of your forum indicated that this question has arisen several times before, but I haven't seen a definitive answer.

I am working in a fairly large worksheet, and I realized that when I make changes to it, sometimes some of the cells do no recalculate. The only way I can get them to recalculate is by clicking into the cell, and then hitting return.
The issue is that I don't know which ones are failing to recalculate unless I click into each individual cell and hit return to see if it changes. This would be logistically impossible given the size of my sheet.
Has this ever happened to anyone else? Does anyone have any suggestions as to how to fix this issue?

What I am trying to to is calculate the number of Years, Months, Weeks, and Days from one date to another. So far I can calculate years and months accuretly but I'm having trouble with the days and can't seem to figure out how to do the weeks.
I'm using the formula: =DATEDIF(B1,B2,"y")&" Year(s), "&MOD(DATEDIF(B1,B2,"m"),12)&" Month(s), and "&(MOD(DATEDIF(B1,B2,"d"),365))&" day(s)"
B1 is the current days date
B2 is the entered date
What I am getting when I enter the date 9/14/09 with the current date (8/3/06) is 3 years, 1 month and 43 days. when it shoud only be 3 years 1 month and 11 days. Any date I enter the days are not right. I can't seem to figure out what I am doing wrong. Also I'd like to get the weeks to come up also. Such as Start date 8/3/06 Entered date 10/19/09. What I want to see: 3 year(s), 2 month(s), 2 week(s), 2 day(s).

I have several data validation style drop down menus, and I basically don't want excel to recognize changes in these cells and execute a calculation of the entire workbook. Since there is a large number of calculations being performed in the workbook the sheet gets really slow.
Overall the way excel "automatically calculates" really screws me up a lot. This built in functionality could be a lot smarter in my opinion.

I have this problem where the SUM function is returning 0. The context is this- I am simulating values using RAND() and looking up the values corersponding to probabilities from a different tables. I then use the TRIM function to return the value I need, and the final number is of a "general" format.
This is the formula in the column I wish to sum:
And this is dragged down the column.
When I change the cells using =VALUE(cell) the SUM function then returns the required value. Oddly the SUMPRODUCT function seems to work.
Calculation is set to automatic and the cell has been formatted as a number.

I know how to turn off automatic and manual calculation modes manually in excel or through VB. But is there a way to make the automatic calculation mode ignore changes in certian cells? It would be good if you could right click on a cell and turn this on/off as an option. I assume I will have to code this in vb somehow, but I am a novice. Something like:
Sub test123()
For Cells = Value.Range("I7:R22")
Application.Calculation = xlCalculationManual
Like I basically want part of my sheet to be set to manual calculation mode, and partially to automatic...

I have a table with rows that keep growing. But I have place formula in the whole of column F, i.e. F2:F66565. When I import information from MS Access into column A to E, the formula in F does not work, until I copy from F2 to the end manually. I have tried using Tools, Options, Calculation, Automatic. That doesn't work, I have also tried F9, that doesn't work and I have also tried checking Precision as Displayed under the calculation tax in Tools-Options, that doesn't work either.

I have workbooks in which summary tables are generated by lookup formulas. Tables are on different sheets but all use the same lookup value by referring to a cell on the 'master' sheet. The lookup value appears in cells on all sheets, by reference to the master sheet (e.g. [formula] = mastersheet!$B$2).
The master sheet contains the main summary table and is copied and detached for distribution, using a macro. For practical reasons, this is done in two stages, first copying the sheet within the workbook (to make minor alterations), then moving it to a new book to save and distribute.
This is where the problem arises. After the sheet has been detached, we find that if we now change the lookup value on the master sheet in the original file, the tables on that sheet will update normally, but the cells on other sheets remain frozen at the previous value and the tables on those sheets do not update.
The only way round the problem is by Shift + Ctrl + Alt + F9. (Maybe I should add that all my workbooks are always set to automatic calculation.)
The macro itself is not the cause of the problem; if we follow the same procedure manually, the result is the same. However, if we move the sheet in one step, eliminating the intermediate copying stage, the problem does not arise. But this is evading the problem, not solving it, and I would be reluctant to have to resort to this.
The original problem remains as stated, viz. failure of automatic calculation.

which will calculate value of a cell when one of the variables has been changed?
To illustrate what I have in mind, an ecxample:
* User can add values to cells using UserForm
- Component name (to Cell "A1")
- Component price (to Cell "B1")
- Component quantity (to Cell "C1")
[Code]....

I have several files of data that are from a data logger. The data is broken up by day. Each day has roughly 43000 rows of data, at its sample rate. This has made charting the data a nuisance. Is there a way to resample the data so it fits in the 32000 points excel can chart? In the future I will set a sample rate that will keep the number of points below the 32K per series. I would like to be able to have the total number of points reduced by averaging the data not by simply deleting one of every four rows.

I have a table that has a list of product names in column A and a list of product types in column B. Starting in Column C, each column represents a date for each day of the week. Each day of the week we run tests on our products to verify their quality. The result of the test is represented by a number. so column C has the test results for each product that was tested on 01/02/2013. Column D has the test results for 01/03/2013, etc.
I need to be able to average the test results of multiple columns for a given product type (column B).

For taking out zeros i am using =sum( : )/(sumproduct(( : <>0)*1))
im trying to use {=average(if( : ="1962", : ))} for each year in date column G and average data in column N.
How would i put this together?
Average each year starting with 1962 without counting zeros.

I want to find the average value for each Jan 1st, 2nd, 3rd ..., for a data set of five years. How do I do this quickly? I can filter, but would have to do that 365 times and involves a lot of pasting. I tried a pivot table, but basically came down to the same problem, although I don't understand pivot tables that well.

I have attached a tiny part of a massive data set I am working on. As you can see in column 2, the data is roughly every 15min for 5 days. The data I am interested in averaging is color coordinated in column 3 (if you scroll down you can see a different color for each day's data set.)
In column 5 the dates are summarized into days as opposed to the 15min breakdown. In column 6 is the problem. How do I get the averages of the relevant data in column 6 in such a way that I can drag the formula down and the next cell will automatically calculate the average for the NEXT day, REGARDLESS of how many temp readings there are, as this data fluctuates from day to day.

I am having difficulty trying to solution this:
Row 1 = Dates e.g. 1-Mar - 31-Mar
Row 2 = Day of Week e.g 1-Mar(B1) = Sat(B2) through 31-Mar ending at (AF)
Column A has hourly time intervals
A3 = 0:00
A4 = 1:00 etc to 23:00
Numbers fall into cells by date/day and interval up to today 10-Mar
What I am trying to do at is average the days separated by Weekdays and weekends..so the formula at AG for interval for weekday would be =AVERAGE(D3:H3,K3:O3,R3:V3,Y3:AC3,AF3) weekends (Column AH)would be =AVERAGE(B3:C3,I3:J3,P3:Q3,W3:X3,AD3:AE3)
I want to average the weekdays and weekend numbers without having to group the weekdays and weekends in a custom sort in the final column. That way when I add the data every day, it auto calculates in AG and AH. If I do it as it shows above, the AVG is skewed due to the blank cells.
Attached a sample worksheet.

I am new to VBA & not sure of the full understanding of code copied from a workbook which worked on the same principle but with Monthly (12) tabs. I thought if modified to show weeks, the macro would be able to locate the current week tab & day/date within - but upon opening, the cell stops at WK19 & column O - rather than WK43, Column N (which changes daily).
Sub Auto_Open()
week(1) = "WK1"
week(2) = "WK2"
week(3) = "WK3"
week(4) = "WK4"
week(5) = "WK5"
week(6) = "WK6"
week(7) = "WK7"
week(8) = "WK8"
week(9) = "WK9"
week(10) = "WK10"
week(11) = "WK11"
week(12) = "WK12"
week(13) = "WK13"
week(14) = "WK14"
week(15) = "WK15"
week(16) = "WK16"
week(17) = "WK17"
week(18) = "WK18"
week(19) = "WK19"
week(20) = "WK20"
week(21) = "WK21"
week(22) = "WK22"
week(23) = "WK23"
week(24) = "WK24"......................................

I was wondering if there's a way to add a formula to calculate week over week % change automatically every week when I enter in new data. see the attached excel file for reference.
What I would like to have is the ability for the formulas in c5 and f5 to be able to auto-update to the newest week and the previous week's data instead of manually having to update it each week. So if I were to add a new row with data for week beginning 12/2, the formula in c5 and f5 would automatically update to calculate the week over week variance. I tried researching prior to asking the question on this forum, and I think it may be possible to do it using the index match function, but I'm not sure how to apply it in this case.
