One of our govt. agencies requires that I compute the 24-month rolling averages of the daily average input to a manufacturing process. In this instance, the agency is demanding the rolling average since 2003, so there are a fair number of data points involved. The process control computer can provide me the daily data (attached file contains 30 months of data), but cannot compute the 24-month rolling average.

I've got daily water level data that spans around one hundred years. I am looking for monthly average water level data, but rather than using the whole month, I'd like to average the first two days and the last two days. I want to have a single value for each month in the 100 years of data.
If the data was smaller I could do this by hand, however having 100 years worth of data = 1200 months = so many days...
It's tough since months don't have a set number of days, and then leap years and it all gets so complicated. I've never really had a problem where date was a criteria to pull values from, and I don't know how to work with this. The internet suggest the Averageif function which I have dabbled with, but no dice.

I am trying to get mmm-yy date format for the next 2 consecutive months from now. I used the following code for that reason, but I am not getting.
strDate = Format(DateAdd("m", 1, Date), "mmm-yy")
strDate = Format(DateAdd("m", 2, Date), "mmm-yy")
However if I use this, I get the current months date correctly (like May - 08)
strDate = Format(DateAdd("m", 0, Date), "mmm-yy")

I have a spread sheet with towns listed in Column G from row 3-81. I months going across row 2 as column labels (they are dates in Jan-14 format). They go from column H-AF.
What I want to happen is to have a formula (not in VBA) which will compare the month in row 2 versus the current month. If it is more than 5 months ago I would like it to return the town in column G for the corresponding row. The only thing I am using to "mark" the last time the town was worked is an X so that is all it needs to look for.

In one column I'll have a list incrementing in 1w,2w,3w,1month and I want to be able to count the number of days that have elapsed till the latest cell. Right now I'm just winging it by saying there's always 31 days in one month using a COUNTA function, but I need it to be accurate.

I need a formula that will calucalte the monthly total based on the following conditions:
Col A = Yearly Cost
Col B = The number of the month when the costs are starting (1=Jan etc)
Col C = The duration or the number of months for which the costs are to spread
Col D is Year 2013 with the months across columns D-O. Row 1 above those columns shows the month's corresponding number.
Right now I have =IF($B3<=D$1,$A3/$C3,0) however if my start month is 1 and my duration is 5, I need the costs to stop after May. I've attached a sample file. Calculate based on start month and duration.xlsx

I m trying to write a formula for my financial model. If anyone can take a stab at a solution. I'm trying to write a formula that will equally distribute revenue either over the next 1 month, 2 month or 3 month period depending on size of the deal.
Details:
Sales will fit in 1 of 3 categories. Less than 25k; between 25k & 100k; greater than 100k.
- if under $25K, recognize in next month (month N+ 1)
- $25K-100K, recognize in two equal parts in months N + 1 and N + 2
- over $100K, recognize in three equal parts over 3 months
N + 1, N + 2, N + 3 ...

I'm trying to average data for the past 3 years. My spreadsheet is setup like this.
Year, NameID, Salary, Average Salary
I have the spreadsheet sorted by NameID so most people in the database will have 3 entries right after another. How do I determine an average salary for the person across all 3 years?
I need the average salary to display across from the most recent date if that is possible as well i.e. if the latest salary date is from 2006, I would prefer that is entered into the row corresponding to 2006 and leave the 2004/2005 rows blank.
Also, some people might only have 2 years of data so keep that in mind as well.

Column A has approximately 50,000 rows with unique property parcel numbers. Column B has numbers that represent an elevation point on the parcel. The parcels are not level. The elevation of a parcel varies depending where one measures. So,...I have many rows with the same parcel number in column A but the adjacent column B shows a different elevation. Is there any way to:
1) remove all of the duplicate column A parcel number rows so I have just one column A parcel number row.
2) get the average of all the column B elevations to show up on the same one row?
I should only have approximately 15,000 rows if I could get rid of the duplicates and get the average elevation. I have version 2007 but I have to share with others who have version 2003. I don't know if that makes a difference but I thought I should mention it

The organisation I wish to report on has many cost centres which each contain many people. These people are on many different grades, and each are on differing salaries (even those in the same grade).
One “reporting group” has many cost centres.
There are several reporting groups.
I need to report on average salary per grade / per reporting group.
I have attached some dummy data. The “rep group” tab displays the reporting groups and the cost centre mappings (ie reporting group England contains cost centres 1, 2, 3, 4, 5, 6 and 7). Note in reality the cost centres are not this simple, they are 6 digits and varying ranges.
In the “salaries” sheet each individual is listed along with their cost centre (in column c) and their grade (column d). Their salary is shown in E.

I have a column of data in Excel in the [h].mm.ss format. These values range from a few minutes to hundreds of hours. I need to get the average of these times.
My code is below. I'm getting a type mismatch error on the line that tries to add the time to the total. The line is in red. I've tried using a Integer, Long, Double, and Date as variable types for this particular variable. All with the same result.

in Sheet1, i have 'part number' listed in column A and 'customer number' in column H. in column P, i have 'customer price' (for that part). so there are multiples of the same part numbers listed in column A.
in Sheet2, i have a summary showing totals for the parts (regardless of the customer), which includes SUMIFs for other columns such as pieces sold, etc. what i am looking to do is get the 'customer price' average by part (in column P/worksheet1) for each part on Sheet2.
Sheet1 sample:
Column A / Column H / Column P
31397 / 1001240 / $6.60
31397 / 1020312 / $6.65
31397 / 40020 / $6.63
31832 / 1047493 / $4.22
31832 / 1035195 / $4.22
31832 / 40017 / $4.40
So for Sheet2 i would like it to be like:
Column A / Column B
31397 / $6.6267
31832 / $4.28
i also need this formula to work if column P has any cells with zero entered.

I'm making up a list of average scores across a season. I have an average column and I need to be able to deduct 10% from this average, then have excel ignore any scores below this new number and make up a new average (kinda like a handicap score).
I have columns for average (BD), 10% of this (BE) "ignore any score lower than"(BF) but Im not sure how to get excel to add up only the scores below the number in BF and make a new average column of only these in BG -
Last column would be to give each person a classification based on cutoffs (for instance 1-10=C Class, 11-20=B Class, 21-30=A Class etc etc). Is there a way to make "if BF=xxxx, make BH A, B, C etc?

i've got a worksheet with 3 columns each declared, called date, place and avspeed
I'm trying to average the avspeed if it falls under certain criteria within the other 2 columns.
The dates are in day format and basically I require the average over the week
If tried using
=AVERAGE(IF(WEEKNUM(date)=45,IF(local=I4,avspeed)))
also declaring it as an array formula but both
also tried the following by summing and then counting the data and dividing one by the other, but so far neither are working

Trying to compute annual change I've always used the formula "(b1-a1)/a1" - where b1 is the current year, a1 is the prior year. I've been asked to compute average annual change over a number of years and thought simply by using the above for each year and then taking the average of all these, I'd be ok. I recently found a formula as follows: "(y2/y1)^(1/n)-1", where y2 is current year, y1 is 1st year I have data, n = the number of changes.
