I have a table of data covering the last 9 months based on values automatically collated from 15 minute intevals.
The date/time is in column A (01/01/2009 00:00) with the data collected in column D.
My wish is to get the average daily data from column D and I am slowly losing my head!!!
Is there anyway of getting a formula to auto-average the daily values bearing in mind there are currently 96 daily entries.
I have tried converting the first 5 digits of column A to numeric (i.e. 31894 for 01/01) then trying to write a formula saying =average(D1:D24577,if(range="31894",1)).
I can now see a simpler way but am so confused after an hour or so of trying.
Each day has 96 readings so I need an auto adding formula. average column cell A would say =average(D1:D96).
Is there are way to have the cell below auto-update itself to look at the next 96 values and so on and so forth?
I need to count the daily average of a task to a week ending number. I need to see the current average after each day during the week. Example – Mon = 2, Tues = 4 AVERAGE is 3 – Wed = 2 AVERAGE IS NOW 2.6…and so on averaging out after each day is added.
I am performing a given exercise every day in the month of march. I have the dates all lined up in my spreadsheet, with the sum at the bottom. What I want to do is have another cell that will give me my daily average of performance. For example today is the 2nd and I have performed this exercise 360 times, making my daily average 130 per day. If I performed 200 of the exercise tomorrow I would have a grand total of 560 repetitions making my daily average roughly 186 per day (the day, march 3 divided by the number of repetitions, 560) and so on and forth.
I need a formula that will automatically calculate that daily average as I progress with the month. But I want the calculation to stop at the end (i.e. I don't want it to continue as the year progresses, meaning the divisor keeps going throughout the rest of the year). Basically, I guess, I am looking to fill in the daily repetition and the divisor to increase each day as I do so. My average is to be displayed in cell B36, so today my formula should read (=2/B36) and on March 31st the formula would be (=31/B36).
I'm working on a time series dataset with a time step of 15 minutes. I need to calculate daily average of the several variables. So let column "A" be the "date-time" column, let column "B" be the "variable column" and column "C" be the "average column", I need a function that calculated in C1 cell the average of B1 to B95 cells, in C2 cell the average of B96 to B190 cells, in C3 cell the average of B191 to B285 etc.
How to go about fixing my spreadsheet so I am not having to manually update it each day..here is my forumla I am currently using...=(AVERAGE($D$2:$AH$2)-C5)*AI5...basically i need the cell below in D2 to change as every day a new day rolls off..for example the following day I need this formula to be =(AVERAGE($E$2:$AH$2)-C5)*AI5 ....so just that day changes.....do I need to use an If/then statement? if so how?
I have a workbook with two sheets - DATA and SUMMARY. DATA has two columns - date and data_value. Data will be added to this sheet on a regular basis
SUMMARY has two columns - month and average
In the column for average I would like a formula to calculate the average of data_value for each month without having to manually determine the range for the particular month.
I have data in the following format (columns A & B):
Code: Day Value 1/1/2002 2.1 2/1/2002 4.8 3/1/2002 0.1 " " " " " " 31/12/2011 5.2
I'd like to be able to write a formula so that I can get the daily data averaged over each month, e.g so that I have something like:
Code: Day Value Jan 2002 3.3 Feb 2002 4.3 Mar 2002 3.1 " " " " " " Dec 2011 4.2
I'd like the data in monthly averages so that I can graph them. I have read about array formulas and averageif statements, but I can't seem to combine them to make them work.
Am trying without success to create a formula to calculate average daily balance from a ledger that has a variable amount of entries per month. The variability of # of entries has me stumped. For example:
I have a spreadsheet that contains developer related data. I want to be able to do a weekly analysis of average construction time and costs. The problem I am running into is properties enter rehab phase and exit rehab phase throughout the week.
For example:
I want to know the average $ spent and total rehab time week 1 of april. I may have 4 homes that entered rehab that week and 3 that move out of rehab that week. Moreover, I need to ensure those homes that entered and are still in rehab for that week are counted. How do I accomplish this feat?
I have a set of 7 years daily rainfall data. I need to calculate the daily average of rainfall from this 7 years data set. I don't wanted to calculate it by for example copying and pasting the first day rainfall of each year rainfall to a new sheet and average it for all the days. I need to calculate it all at a time.
I have two time series which span several years. The first series measures stock levels on every Friday (52 values a year). The second series measures the price level every weekday (260 values a year).
I'd like to condense the daily data in to a weekly average, can I do this easily? For example, I could manually use the Weeknum function to calculate the week number of each daily price data, then find the average daily price for each week, thus giving me 52 values which I can compare to the weekly stock series. Is there an automatic, fast way of doing this? Alternatively, I'd be happy to settle with a monthly average. Is this possible via macro's or does VBA need to be used?
I've set up a simple spreadsheet to keep track of my food expenses every month. The first column is for the date, the second is for the daily total expenses and then the next three columns are where I add the data which is then calculated into the daily total column.
I also have a total at the bottom for the entire month. Now what I want to do is I want to also have underneath the grand total, a cell which keeps track of my average daily expenses. Basically I want to divide the total expenses by the number of days which I've entered data. Now normally this would be fine but because I've applied the formula to all the cells in the expense column, it automatically lists every day as "0" rather than leaving it blank. So when it does the average calculation it's dividing my total by 30 days rather than by only the 7 days I have data for.
I need to monitor the average daily usage of a liquid tank for a customer. We fill this tank every few weeks. The formula I am looking for would ignore the fills and just count the daily usage.
I create this spreadsheet as a loan schedule using average daily balance method. (1/payment is constant, fortnightly 2/interest is 5.5% per annum)
In the interest column, at the beginning of each month ( when the day is 1) the interest will be added up from calculation of previous month daily balance.
My idea is that at interest column(let start at 1/08/2013) if (day(A49)=1, average the 30 or 31 cells above E49, 0). I will manually make adjustment for February where 28 or 29 days applicable.
I want it to average based on month and year. I have daily data and want to average everything for say January 2000 into one cell and February of 2000 and so on. Column A has date (mm/dd/yy) and column B has data.
the macro will track daily min/max values, and keep a count of the times these values occurred in a separate sheet in the workbook. At first I thought simply setting up a macro to look at a predefined range of rows to find the min/max values, but some days may be missing data; therefore, I need a macro with the logic that looks for the min/max value appropriate to each specific day (which is the tricky part). Below is the detailed explanation of the process.
1)The "Main" sheet, Column A, contains days 01/05/1999 – 01/29/1999 (days are already in numerical value format). Begin in A1 and this will be the first daily value. Find the Max Value in Column D corresponding to the numerical daily value of A1. 2)Once Max Value found in Column D, Column B of same row will have the time the Max Value occurred. 3)Count time Max Value occurred in “Time Count” sheet Column C of corresponding time. 4)Move down to next daily value. Continue this process to last row in sheet.
For example, “Main” Sheet, day 01/05/1999 (numerical daily value 36165), Max Value is 1.1835 found in Cell D12. B12 has the time at 2:45. A “1” is then placed next to 2:45 or C14 of the “TimeCount” sheet. If the next day’s Max Value occurred at the same time, then a 2 would be placed in C14...........................
I have an excel file that I use to track all my financial investments. The file is already set up with a query to retrieve stock prices when I refresh the document.
I would like to be able to open up the document, and store the closing price of the stock(s) with a date in the next column over. With this information I can graph weekly, monthly annually, or any time period I want.
I have been searching for a couple of hours now, and I could not find anything similar to this. I would think this is a pretty common idea for many people tracking their investments with Excel, so if it has been covered perhaps someone can point me in the right direction.
I don't have any programming experience in excel so as detailed of an explanation as possible
Is there a formula that would allow you to take the average of all values within a range but not count the zero values? I thought something like this might work but it's not. Neither one worked.
See the attached excel table. I need the cell E4 to keep adding the values typed in the cell D4 on daily basis.The cumulative shouldn't be changed if there is no value in the cell D4. E4 should accumulate and keep the totals typed in D4...
I have a list of values on my spreadsheet in a similiar order to this:
17.91 16.59 15.00 14.86 13.56 12.17 11.01 0.0
I use the average function to work out an average for all the values, but since the value of 0.0 is showing i should not include this as an average. the range of values above (8) will always be the same for the month - so i need to find a way of omitting the 0 value without keep changing the formula
I have a column with values from P2 to P3077. I need a formula that would average values from P2:P6, P7:P11, P12:P16 and so on till the end (that is 5 data points each time till the end).
Column B: The day of the week that the date is, Sunday, Monday, etc. Column C: Every date in 2008 Column D: my data (the number to be averaged)
What I need the formula to do: Look in Column B for every instance of "Sunday", and count them up (they count only if the data in column D is not 0) and use that number to average the number in column D
So if I have 52 Sundays and we are only 4 weeks into the year and the 4 data points are 50, 100, 75, 25. The average will be 62.5 instead of 4.8 (divided by 52).
I was wondering if anyone could help me with the following problem:
I have a clumn of numbers, let's say 100 numbers. I want to extend the column to 200 numbers (spread it out so to say). One way is to insert the average of two adjacent numbers between them, but how would I do that in Excel?
I would like cell B2 to show the average of the next 5 non blank values in row 2 (C2-Z2). The problem is there are varying blank cells (non data points) depending on each row. So i need the forumula to account for just the first 5 immediate non blank cells.
I have Column A which is an Employees birth Year, Column B which is salary, and Column C which is a list of Years.
I need a formula to read the Year in Column C, refer to Column A finding all the rows that match that year, than refer to Column B (salaries) and find the average of the salaries.
