The average of the first 10 cells is now AVERAGE(A4.A13) = 5.5

I would like to enter one formula in say cell A1 that will calculate the moving average in the first ten cells each time a new entry is added. Naturally as needed, new rows are added below cell A1. I hope my problem is clear.

as I have been unable to solve it myself. I have tried using offset but have been unable to resolve the issue.

I have a worksheet that has all weekday dates in column 1 and values in column 2. I want to create a 30-day moving average based on the last (non-zero) value in the column 2.

Since every month has a different amount of days, I want it to search the date that has the last value (since I don't get a chance to update it daily) and go back thirsty days from that date and give an average of all the column 2 values skipping and values that are null or zero.

I have a pivot that includes customer data and I need to create an average for each row based on the first populated column for each customer. After one month of units appears for the customer, I need to calculate the average going forward, and if there are blanks after that they should be treated as 0 in the average. Below is an example of my description of the pivot.

Jan Feb Mar Apr Customer #1 1 1 3 Customer #2 1 3 Customer #3 2 2

So, the average for customer #1 would be calculated from Column B to Column E, and factor column D as a 0 in that calculation. Customer 2's average would start in Column C and go to Column E, and factor column E as a 0 in that calculation. Customer 3's average would start in column D to column E.

How do you calculate the average of the last 20 values in a dynamic list? The list is in column A and updates every day by adding a new value in column A.

I will do my best to explain but just in case I have attached a worksheet to make things easier. I have a list of a few thousand products with data on each product. When I run through a series of cuts, I get a subset list and want to be able to calculated a weighted average by somehow saying to do a weighted average (and/or count, and/or average, etc.) on the characteristics of only the products in the subset.

My attached files contains stock returns for companies. Each sheet contains the returns over a 5 year period for a certain stock, with the ticker symbol of the stock used as the sheet name. I want to write a sub that presents the user with a user form. This user form should have an OK and Cancel buttons, and it should have a list box with a list of all stocks. The user should be allowed to choose only one stock in the list. The sub should then display a message box that reports the average monthly return for the selected stock.

I have an excel work book with 6 tabs. I would like to have Excel move an entire row from one tab to another tab (removing the row and inserting it in the other tab). I.e. Example I have a tab with items that are marked as "Open Actions" so if I were to change the drop down to close. Excel would move that entire row of actions to the tab with the "closed actions" and insert into the next available row. Now if someone were to come back at a later date say no it should be reopened than I would change the drop down to open and excel would move that row back to the open actions tab into next available row. I tried a PIVOT table and no good I played with few macro and not.

I have obtained a function (from this site at Exponential Moving Average) which is supposed to help calculate simple mathematical values but it's not working on spreadsheet. assist with taking a look at this as I have attached the spreadsheet?

I have a set of data in column A consisting of over 1200 numeric values. The problem is that there are some blank cells in this column: Colums A data:120, blank, 135, blank, etc I need to calaculate the average for the first 25 data and then claculate the average for the next 25 data set dropping the first 5 and adding new consecutive 5 data ignoring all the bank cells!, so if the first statemnet is : averagre (a1:a24), the second statmnet should read (a6:a:29) not counting the blank cells. I don't know what array formula can be used to do this job for me.

I have done quite a bit of looking on Google and looked over the posts in this forum, however, I can't find an example Excel worksheet for a linear weighted moving average.

The data set I am applying this to has 180 data points and the linear weights should extend back over the last 30 points.

I am using the built in moving average function to calculate the moving average of a set of numbers. There are a few things that i would like to do.

First i would like to have the last result displayed in a single cell. Then next to that cell i would like to have a cell that would specify the period of the moving average. I would like to be able to change the period in that cell and have that change it in the actual function. And finally i would like to have the moving average in a chart that would also change its period once that is changed in the respective cell. I realize that this might need some VB coding which i am currently learning.

I have a column of data that contains various blank cells where no data was measured. In the adjacent column I want to take the moving average of the last 4 data points including the most recent entry. My problem is i do not know how to handle blank cells where there was no data. I need it to average the last four in the column where data acutally exists. I am ok with using helper cells if needed and I am not worried about the first four results at this time.

The following code works fine if the data is sorted from oldest to newest. I need for it to work when the data is sorted from newest to oldest. For this to work, I would need a change that works something like this: "total1 = total1 + close_(a, 1) * a" would be "total1 = total1 + close_(a, 1) * b" with "b" incremented in the opposite direction of "a". I code very infrequently & have tried a lot of different things, searched the Internet, etc. all to no avail.

For instance, with "close" data in column "I", the data sorted as follows works with the formula "=WMA(OFFSET(I2,0,0,9,1) )" to correctly return "791.50", but the opposite sort returns the wrong number.

The correct calculation is: (807.19*9+798.38*8+793.81*7+793.06*6+776.28*5+769.48*4+773.2*3+789.01*2+793.87*1)/(9+8+7+6+5+4+3+2+1).

how do I perform calculations on the last x non-blank instances in a data range? for example, let's say I have a spreadsheet of 5 baseball players' batting averages (rows are team game number played, columns are at bats and hits for each player). I want to see how each player has performed in their last 10 games played, but some players have not played in every game. If I just use the sum function for the last 10 cells, I won't get the correct information for any player that has missed one or more of the last 10 games.

Currently i have a spreadsheet with realtime data feeds from Bloomberg (or reuters). What i would like to do is:

a. Fill a vector/column of data values every minute until we have 30 observations i.e. from 9.00am till 9.30pm

b. This will then allow me to calculate a moving average of the last 30 (1 minute) observations.

c. At 9.31am, the 9.00am value drops out of the column and is replaced by the observation at 9.31am. This results in a constantly updating column of the last 30 minute observations and will allow me to have a realtime moving average.

I need to build a macro which copies 3 rows every day and pastes the row data into an identical sheet. The three rows will have column "D" as =today(). As the days progress the three rows will change accordingly ( tag to the today's date)

e.g. 28/1/2014 28/1/2014 28/1/2014

I need the macro to recognize the date when pressed and copy the corresponding rows of data and paste them into an identical sheet with the same date. The second sheet is an archive sheet. The date will tick over as per the calendar.

removing duplicate rows and move other data frm rows to columns.xlsx.

I am attaching a sample excel sheet showing what I need to do.In the first tab, I have a list that includes duplicate rows (first column only). I want to remove those duplicate rows but I don't want to lose the data in the following columns which can be unique or duplicates as well.

see the desired result tab in the sheet to get an idea of what I am looking for as the end result.

Keep in mind that the actual source file I am working with could have up to 50000 row, and the expected results could be around 2000 rows. So nothing can be done manually.

I'm trying to create a .cvs file from an exported excel report, but before I can import it to a database I'd like to have one row per record.

I've already omitted out the headers and footers blank spaces and unnecessary columns from the excel file and I needed to just combine multiple rows into one.

how to find the average times of two different sets of groups. There are the baseline times and intervention times. Both groups have three subtopics: Time Fell Asleep, Woke Up, and Duration (how many hours I slept). I am not sure how to find the average of each subtopic. Here are the times....

I want to calculate the average for 6 cells across 6 different worksheets.

For instance in sheet 7 i want to calculate what the average of sheet 1 A1, Sheet 2 A1, Sheet 3 A1, Sheet 4 A1, Sheet 5 A1 and Sheet 6 A1 is. However some the cells contain blanks/zeros which are resulting in an error message. The overall figure still needs to be divided by 6 to get the average.

I need to find the average time it takes students to take exams . I use the following formula =text(end time - start time, "h:mm"). I am able to calculate the amount of time it takes a student to take the exam. Now I need a formula to calculate the average time students take to complete a test. I have over 80 times i need to average. Whenever i try a formula I keep getting 0.

I have a pivot table showing actual and forecasted sales per month for diffrent regions/sales channels/segment.

I would like to calculate the average monthly sale, for forecasted and actual data, within the pivot instead of doing it outside in columns to the right of the pivot table.

I have an array formula in the attached file to calculate the average of the Top 3 (cell F6). I put that same formula in cell F14 to calculate the average of the Bottom 3 (just change the "large" to "small", however it doesn't work. The result shows zero. How do I fix this?
