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'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.
View 3 Replies View RelatedI'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 calculate SUM and AVERAGE of rainfall for each and every year separately and must be displayed separately in a separate column. For your easy understanding, I have done manually and attached the excel sheet.

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.

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).
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:
date, amount
1/1/2005, 10
1/5/2005, 1
1/10/2005, 4.65
1/18/2005, 7
1/22/2005, 20
Aver Daily Bal = 23.78. and I can get this easily manually, but I'd like a more automated solution. I'm trying a sumproduct angle, to no avail.
Any way to enter in a total amount of time and then subtract it from a time shown. So for example:
I want to enter in a time of 26 hours, 10 minutes and 2 seconds: 72:10:02
I cannot find a format that allows me to enter the hours in excess of 24
Then I want to subtract it from a time of the day which will be entered as AM/PM: 02:40:02 AM
Then I want to show the result as a time of day: 00:30:00 AM
Lastly, I want to also show the amount of days adjustment: -1d, 00:03:00 AM
How this can be done through cell formulas?
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?
HOW TO MAKE DAILY AVERAGE IF I HAVE DATA SET WITH 15 MIN SETS
View 3 Replies View RelatedI 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 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.
View 9 Replies View RelatedI 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.

Some years ago I came across a formulae to calculate Daily Interest on a Building Society Savings account in the UK. I have used this since but find my calculations never work out the same as my BS, although to my advantage! It is =B3*B4/360*DAYS360(B5,B6,TRUE) Where:
B3=Capital
B4=Interest Rate
B5=Starting Date
B6=Finishing Date
For some reason the formulae uses 360/year and not 365/year. Using both still gives wrong answer.
I am trying to set up my excel to calculate daily compound interest.
The amount is 10,000 at 0.75% per day for 6 months.
I have tried several different things with no success -
calculate overtime hours from daily time entries.
Normal hours are 7.6 per day
Time 1/2 is hours over 7.6 but no more than 2 hours
Double Time is all hours over that.
I have the spreadsheet with the days of the week in one row and at the end I have 1 cell for Normal Hours, Time 1/2 and Double Time. I need a formula that will work out overtime off each day and add for all days of the week and enter data into one cell. So all normal hours are in Normal hours and Time 1/2 and Double time are automatically calculated once hours are put in per day manually.

I currently have a profit/loss spreadsheet where I use a SUMIF to calculate daily gains/losses.
=SUMIF('Daily Sheet'!B:B,B377,'Daily Sheet'!H:H)
Basically, on the 'Daily Sheet' page when a sale is made I write it in a row. Each sale gets its own row. One of the column's has the date. (Column B) Column H has the respective gain or loss for that sale/purchase. B377 in this case contains the date 18-Nov. (B360 to B389 has Nov 1 through Nov 30) So this cell will calculate all the gains and losses in column H for each sale/purchase entry I have for that day. Some days I have 30 rows, others only 2 or 3, so this works great.
My problem now is that my rows have gotten much more complicated and detailed, and now I'd like to be able to only sum column H:H if it meets TWO criteria. (I'd like to add in Column C that specifies the type of sale or purchase being made, which is R, T or S for my purposes.) So I'd like to somehow write a sumif that only adds up the sales for 18-Nov AND sale type R.
I have a spreadsheet called PRODUCTION, where information is entered daily. I need weekly totals (mon - sun) to be extracted into another worksheet.

Right now I have it 'mostly' figured out, but under certain conditions, it calculates more than 8 hours in one day for straight time. Is there a way to set a maximum value for the straight time cell and have the difference be added to the overtime cell?
I've daily data of a stock indices returns and I would like to calculate the monthly standard deviation. Currently, I'm using the following worksheet functions: =STDEVP(C2:C20)*SQRT(COUNT(C2:C20))
However, the range changes from month to month, which makes the process of calculating the monthly standard deviation to be quite tedious if I've about 10 years worth of data. I assume I could somehow substitute the range with a dynamic range, but I'm struggling to come up with the correct formulation that would do that.
