# Sum Of Squares Calculation

Jan 16, 2008
I'm trying to do a sum of squares calculation, between and within groups, across multiple columns.

I llike this to occur automatically when I input the data. Where I've running into difficulty is calculating the mean of each group(without sorting and manually selecting). See sample of data below:

Typestdby_currentrx_currentNormal0.141116170.171218Rework0.140827160.170686Normal0.140360580.172524Rework0.136112870.167756Normal0.141427740.170232

Note that there are more columns of different parameters I've just inserted two for demonstation

How would I add the squares of cells A1:ZZ1 or A1:A1000, without having to do

=SUM(A1*A1+B1*B1+C1*C1... etc

This is a basic example of what I actually want to do, but is essentially the same problem.

I need to do a Sum of the Squares of the first 'n' Natural

Numbers. Something like:

function_name(n)

If 'n' is 8 say, then the function would return 204.

Thats 1*1 + 2*2 + 3*3 + 4*4 + 5*5 + 6*6 + 7*7 + 8*8

Likewise if 'n' is 6 say, then the function would return 91!

I have a lot of lists of integers and I want to sum their Xth power automatically, for X = -3, -2, -1, -1/2, 0, 1/2, 1, 2, 3, 4, 5, 6.

For example, take this short list of integers: 1 2 3 4 6 12

The sum of their Xth power must be: 1^X + 2^X + 3^X + 4^X + 6^X + 12^X

How can I do that?

In a userform i have created an textbox. The user types some text in it and after clicking an OK-Button this text must be copied to a cell To allow multiple lines (enter = new line in textbox) i have changed the textbox property EnterKeyBehavior to True. The problem is that after copying this textbox1.text to a cell in see square blocks in the cell.

line1[]

line2

instead of

line1

line2

I use the following code to copy the text into a cell:

Private Sub CommandButtonOK_Click()

Dim TextboxText As String

TextboxText = TextBox1.Text

ActiveCell.Value = TextboxText

Unload Me

End Sub

how to avoid this [] (should be like alt-enter in a cell)

Formula used for untouched - B2+C2-D2

SLA Target Min - 98% and Max 99%

Algorithm - (Total Number of Allocations completed within 5 business days Plus Type A Exclusions) / Total Number of Allocations received minus Type B Exclusions) * 100

I need a individual SLA achieved % which includes untouched too.

Hoping someone might be able to kindly help me out with this one. It's for a spreadsheet of call charges (credit crunch thing).

On the sheet, I have the call charge up to an hour ($H$5). Over an hour, it's charged per minute at the rate in $H$6.

In cell E27 I can enter the number of minutes for the call.

So basically, if E27 is up to a value of 60 then the cost is just H5, if the value in E27 is 61 or more then it's H5 + (E27-60)*H6.

I'm thinking it's an 'IF' but keep making a mess of it...

How do I calculate YTD from 1 MTD cell? The YTD cell needs to keep a running total of the MTD cell. If the current YTD cell has the number 11 in it and I typed 2 in the MTD cell the YTD cell needs to increase by 2.

What I need is to add a field that gives a gross margin percentage for a project.

To begin, I simplified the following data that the Pivot Table is using. Project (10 different projects), Account Number, Account Category (Revenue, and Cost), Debit Amount, Credit Amount, and a manually inserted column named Total (CR Amount - DR Amount). See 1st image. Pivot1.jpg

I have designed the Pivot table so it lays out like this. Pivot2.png Pivot3 (2).png

I have been trying to enter a calculated field that would automatically provide the Gross Margin Percentage. In the 2nd image, the Grand Total is the gross margin, but I am unable to use that as a selection when creating a calculated field.

I am trying to figure out the calculation steps that Goal Seek is doing behind the scenes so I can create the formula rather than clicking on goal seek whenever I need to make a change. I need to maintain certain weeks of supply every week depending on the sales. Let's say i want to maintain 5 weeks of supply every week, I would like to insert a column for "Suggested To Order' column that would change if weeks of supply goes below 5. In this scenario I would do a Goal Seek, but I want to automate the calculation so I don't have to do this step every week.

I have a spreadsheet with several formulas where I have to go into each one of them to activate the calculation. I use F2 and enter. Automatic calculation is on. Do any of you know how this can be done automatically. A VBA-code will fit the purpose.

My understanding of Excel is that the calculations are performed in Column A first and then down through the rows in Column A. After all the calculations are finished in A, the calculation moves over to Column B and down the rows in B. Is this true?

I know that Excel is a little more complicated than that especially when it creates a queue for calculations, etc. However, assuming there's no calculation list/queue, would the above be correct?

I'm creating a spreadsheet to calculate materials with the following columns Cost/10% of Cost/Customer Cost/Qty/Total cost.

I understand that whilst showing rounded to 2 decimal places excel stores more than this in the cell. which then throws out the Total cost by a few pence.

My research leads me to believe I need to use the ROUND function but I'm unsure which cell to use it or how.

I use VBA with the macro recorder. Now I'd like to programming a code to calculate the average of three cells.

I've done a lot of measurements about 180 but it can be also more. For one test object I've always done three measurements to get then an average.

My values are beginning in cell C2:CXXX, D2:Dxxx and E2:Exxx. For example I'd like to get the average from C2:C4, D2:D4 and E2:E4. The result of C2:C4 I'd like to have in cell H2, the result of D2:D4 in cell I2 and the result of E2:E4 in cell J2. Then the next calculation is C5:C7, D5:D7, E5:E7 and the results in H3, I3 and J3. And so on.

I've attached my excel file, maybe I didn't explained it well. The VBA-Code is for sheet Export.

I got a work sheet with 672 columns of information that im trying to cross compare against. I wanna compare each column against every other column in that row. I have 200 rows of data. That means each i need excel to do 226,128 comparion calculations each row. So that means in the entire work sheet its gotta do 91 million comparisons. Im on a dual core 1.8ghz core 2 duo cpu and 2 gigs of ram on xp pro with excel 2007. I even bumped up my virtual memory by 3 times the size it was yet still its taking forever.

Its taking over 3 hours to do this whole page of calculations. So i opened up visual c++ and quickly programmed in the same code with some generic values and within 3 seconds it computed it all. My guess is that the bottle neck is when excel has retrieve data from the cells because other than that i cant figure out why its so slow. Heres a section of my

I need to find out the amount of time between two dates for filling out

funeral benefits. The form asks how long the person has been alive in Years

Months and Days.

I would like to know if I put for instance 10/21/1955 in say A1 as the birth

date and 01/25/2006 in B1 as the date of death. So what is the formula, if

one, to calculate the time in years months and days that has passed between

the two dates?

I am writing a formula to calculate the last and next month end e.g. if I

enter 28-02-06, the expected result will be liked 31-01-06 and 31-03-06.

28-02-06 will be stored in cell A1, and my expected result will be displayed

in A2 & A3.

My formular is liked " =A1-31 , = A1+31. But because of "31"

has to change each month, therefore if doesn't work to my calcaulation.

Also, from the above example, the calculation for March is correct "31-03-06"

but the January is worng, it comes date on 28-01-06. But I need both result

at the end of the month.

I have been burning brain cells trying to figure this out.

I get these numbers from an online source and they come in like this:

A B C D E

1/1/0912:01AM02:40AM11:18AM07:55PM

The times do not come in as times...when I format the cell to time it doesnt change...that is my first problem.

What I would need to do to these times is: take B and C and find what time is in the middle of them and put that in a different column.

This mess will also need to be plotted on a chart with time by the minute for one day as the X axis. In my example I drew lines on the chart to show what I mean....the blue lines I dont want charted...I use those to find the time in the middle.
