Calculate Average Of A Specific Subset Of Cells Within A Given Range |
Calculate Average Of A Specific Subset Of Cells Within A Given Range - Excel |

I have columns of varying lengths. I would like to average the values within a defined fraction of each column. For instance, if I wanted the first 20% of the length, I would want average(A1:A5) of a column with 25 values, but average(A1:A10) for a column with 50 values.
I can use count() to determine the length of the column of values.
How can I specify a range of cells based on the result of that calculation?
Thanks.

Basically, I've got a sheet that contains a table of entries, and each entry gets a date stamp in the first column. I would like to have the sheet display the average time, in days, between entries. Is this possible?
Thank you in advance!

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:
01/01/2007
02/01/2007
03/01/2007
I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.
Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!
Many thanks,
Caitlin

For example, if I have a total of 53 calls and the total talk time is 4:19:05, what would the average talk per call be? I tried doing everything in seconds (this would give me a total of 15545 seconds) but the total I was getting is 4:89.
What would the formula be to get the correct average time?
I have a table with various percentages, and I would like a formula to have an average of these. Please see attached file to get more of an idea.
Thanks

Is there a formula so that when I drag C1 horizontally into D1, E1, F1, ..., the values placed in each cell will be =A2, =A3, =A4, ...
I do not want to transpose the values from column 1 into C1, D1,.... I want these cells to have a formula that links them up to column 1's values
Thanks
would really appreciate anyones help with this.
I have a column full of text-formatted fractions...
4/5
6/4
3/1
2/5
4/5
etc, etc.....the column is very long!!
I need to convert these to actual fractions...ones I can add to equations, allowing me to multiply and add.
If I highlight the column and goto "format Cells" and change to fraction, the values still stay in the left of the cell.....its only when I manually click on each individual cell, then tick the little green tick, does the cell validate, and the value in the cell moves to the right (and is therefore a proper value).....problem is I have to keep doing this for each individual cell.....and I have 70000+ cells in this column!
Any suggestions on how I could speed this up?
thanks
How can I do this? I only seem to have the options for sums, counts, etc. There are no options for just presenting the data.
So for example, rather than a PivotTable that results in counts of 1, 1, 1 in each cell, I want it to show Compay1, Company2, Company3, etc.
I am trying to make excel automatically add a leading zero to values which are 5 digits long;
i.e. number input is 15185, then excel automatically changes it to 015185.
If I put a Customer Number Format of 0##### it works, however, a user could put any length of number into these cells, and if the number is less than 5 digits I don't want a leading zero.
Is there any way of writing a small macro to sort this out.
The numbers would be input into range B16:223.
Many thanks,
Andy
it as a drop-down list, you can select a name from the drop-down and it's
corresponding value will be added to separate cell? Basically, I have survey
questions which have five possible responses: Excellent - Very Good - Good -
Fair - Poor. We want to assign a value to each, 5 for Excellent, 4 for Very
Good and so on, so that when a response is selected from a drop-down, it's
value appears in a separate cell (so that we can calculate a total and
average score from the selections).
Thanks

I have three columns containing last name values from 3 different sources that I've brought into one sheet. I am trying to find a way to compare all three values to establish if they are the same.
Of the three values there is no master, Each value may be different. So essentially it would be like doing =IF(a1=a2=a3,"match", "nomatch")
But of course this isn't possible.
I don't care about obtaining detail about which value matches which. I just need true or false response as to whether all three values are the same or not.
Thanks for any help anyone can provide.

I'm looking for help in building a formula which will sort numbers into different "buckets". My spreadsheet has a range of values in column B. These values can range anywhere from -100,000,000 to +10,000,000. I'd like to be able to sort them into the following buckets:-
I have various cut lengths that I can pick from...
14'-10".....13'- 9".. 12'-8"........(up to 6 different lengths)
I need to know the best combination of lengths to cut the long bar into to have minimal scrap left when we get to the end of the 550 feet.....
Cut as many of the longest cut lengths possiable.....Cut as few of the shortest cut lengths possiable
Due to the fact that I will have to convert this to a PLC application when completed, I want to find a mathmatical way to do this inside excel and not use the "solver"....Assuming that I/we can come up with an equation to do this .....
Any and all advice/help would be appricated.....
But it gets even more weird. When I click on the Column C cells and then it shows the formula up top in the formula bar and if I put my cursor anywhere in the formula bar and hit Return the formula does not change however the correct value then appears in the Column C cell. It is like the act of putting the cursor in the formula activates it to work properly but until it is activated that C cell shows the value of the cell which it was dragged down from.
This is quite bizarre. Has anyone ever seen this before? I have no idea what is going on. I ran a scan for viruses and none were found. I tried it on several new/different spreadsheets but it keeps happening.
Thanks for any tips on this.
I am new to using Excel and I am not very computer literate. I am looking for some help with a spreadsheet I am making. Here is the problem:
I have a column of 14 numbers in cells A1 to A14. If all of these values are less than 2%, I would like a "Pass" to display in cell B1. If any of these values are greater than 2% I would like a "Fail" to display in cell B1.
I have got a formula that works for a single cell but I can't figure out how to get it to apply to more than one cell. For example, I have entered =IF(A1<2,"Pass","Fail") in cell B1. Now if the value I enter in A1 is less than 2, it shows a "Pass", and if the value in A1 is greater than 2 it shows a "Fail" in cell B1. How can I get this to apply to all of the cells from A1 to A14?
If somebody could help me out that would be great.
Thanks,
Randy

how to count number of occurances where value of 1 is 3 consecutive times? Obviously answer is 3 in this instance but is there an excel formula to count/sum this?
Thanks in advance
Try this...
There are some valid datas in the cells A2 (Eg. 100), B2(Eg. 200), C2 and D2.
Data validation is used in cell K2 to limit it to a set of values.
Can we implement this formula?
IF(K2="Approved")
{
A2=A3; B2=B3; C2=C3; D2=D3; K2=K3;
}
ELSE
{
no change to any values.
}
Thanks in advance...
Cells accept hours over 23,
Adding cells in column returns correct total time.
Have not found a way to multiply these cells by a $ hourly rate.
So use HOUR(cell ref) and MINUTE(cell ref) to capture values in referenced
cell - then use these values to calculate total payment for $rate per hour.
However, the HOUR(cell ref) formula returns the hours in excess of 24 when
the cell contains an hour value in excess of 23 (ie 27 hours returns 3).
I am brand new to Mr. Excel and would love some advice.
I searched the boards pretty extensively but could not find what I am looking for...I apologize if this is a duplicate.
I am using Excel 2007
How do you automatically add rows and update values for cells to a linked worksheet in which rows have been added? For example: Sheet 1, columns A & B are linked to Sheet 2, columns A & B. Sheet 2 has values in A1:A5 & B1:B5 and Sheet 1, since it is linked, has the same info. I want to add a row in between 3 & 4 on Sheet 2 and want Sheet 1 to automatically add the same row and update the value of the cell in column A & B.
Any help is greatly appreciated!
