I would like to arrange a list of values randomly with a formula automatically.
My data has repetitive values.
Sample data in columns A:E
Data
4 6 8 0 0
1 5 5 7 9
So when randomized, in columns I:M, it would look something like this:
Randomized Data
6 0 8 4 0
5 1 7 5 9
I tried something with rand and randbetween, and found a formula but it doesn't work repetitive numbers. Can I get any suggestion please? thanks.
You can use a combination of RAND, RANK and INDEX:
The strategy is to create a vector of random numbers, calculate their rank, and then use this rank to read off the columns on the data set.
In the above screenshot I used:
=RANK(A4,$A$4:$E$4)
in A5,
=INDEX($A$1:$E$2,1,A6)
in A8, and
=INDEX($A$1:$E$2,2,A6)
in A9.
It might be possible to get this down to a single array formula, though the result then wouldn't be very readable.

I have a list of part numbers that are used in 4 different top level assemblies. The parts can be used in 1 to 4 of the top level assemblies. I'm trying to write a formula that will count how many unique top level assemblies a part number occurs in. I had previously written a formula that worked, but it uses UNIQUE and FILTER, and my coworkers don't have Excel 365, so those formulas aren't supported for them. I've been trying to come up with a workaround and would really appreciate any help :)
I have an example (I can't provide any real data) section of our spreadsheet and an image of the formula I had that was working

=SUM(--(LEN(UNIQUE(FILTER(A:A, C:C=C2, "")))>0))
Picture of the excel sheet
Picture of working formula
Use the following formula in row 2: =SUMPRODUCT(--(FREQUENCY(IF($B$2:$B$20=$B2,$A$2:$A$20),$A$2:$A$20)>0))
*I think it doesn't require ctrl+shift-enter in older Excel versions, since SUMPRODUCT is an array formula by default.
The formula checks the frequency of values in column A where column B matches the value in the current row. It returns the count per unique value meeting the condition. Wrapping it in -- & >0 returns 1 for each unique value. SUMPRODUCT sums them.
Edit:
I realized that the top level assembly values are actual text, not numeric values. In that case (since it's all numeric values stored as text) you can use this workaround:
=SUMPRODUCT(--(FREQUENCY(IF($B$2:$B$20=$B2,--($A$2:$A$20)),--($A$2:$A$20))>0))
It converts the text to numbers.
Sidenotes to this workaround:
If any value would contain a character other than numeric it will not get counted.
If you have both values like 02554 and 2554 they'll both get converted to 2554 and counted likewise.
Edit 2:
For text use the following:
=SUMPRODUCT(IF($B$2:$B$20=$B2, 1/(COUNTIFS($B$2:$B$20, $B2, $A$2:$A$20, $A$2:$A$20)), 0))
Please forgive any errors or shortcomings in this question, it's my first on stackoverflow.
I have two sets of data in Excel of differing lengths and frequency, and would like to be able to place a value of 0 for where they don't synchronise, and match the rest.
For example, dataset 1 could be:
Date Set1
01-01-2010 10
01-03-2010 4
01-04-2010 8
01-05-2010 5
01-06-2010 10
01-09-2010 12
01-10-2010 9
01-11-2010 4
And dataset 2 could be:
Date Set2
01-03-2010 102
01-06-2010 104
01-10-2010 102
I'm looking for an output table that displays the values alongside each other for dates matching, 0 otherwise, like so:
Date Set1 Set2
01-01-2010 10 0
01-03-2010 4 102
01-04-2010 8 0
01-05-2010 5 0
01-06-2010 10 104
01-09-2010 12 0
01-10-2010 9 102
01-11-2010 4 0
I can't seem to be able to crack this with my limited knowledge and the lack of synchronisation in the data. Any help would be much appreciated, thanks.
You can do this using a VLOOKUP nested in an IFERROR statement.
The two equations used (and dragged down to last unique date row) are:
H3 = IFERROR(VLOOKUP(G3,A:B,2,0),0)) & I3 = IFERROR(VLOOKUP(G3,D:E,2,0),0))
This will not work if you have duplicate dates in the same data set with varying values since VLOOKUP will always return the first matched value (reading top down).
Place Set1 in A1:B9 (header in row 1). Add a column of zeros next to it in column C, so A2:A9 is dates, B2:B9 is values and C2:C9 is zeros.
Place Set2 (without the header) in A10:B12; move the Set2 data to column C and put zeros in column B, so A10:A12 is dates, B10:B12 is zeros, C10:C12 is values.
Sort the range A2:C12 by Date (column A).
Easier to show with a screenshot but newbies are not allowed to post images.
So, I have this problem, I would like to find the average of a column by using the OR function to check criteria from adjusted columns, I tried putting OR into AverageIf function, fail, also tried the "Average(IF(OR(" again not the correct return. Thought it is a simple thing could be done easily but don't know why it doesn't work. So my table is something like this:
ID: Rate Check 1 Check 2 Check 3
1 5 1 1 1
2 3 1 1
3 2 1
4 4
5 5 1 1
6 3
7 4 1
I would like to find the average of the rate column by checking if there are any value in either Check 1; Check 2 or Check 3 columns, so in the above case i will get the average of all but row with the id 4 and 6. Is this possible without using a helper column?
You can use SUMPRODUCT()
=SUMPRODUCT(((C2:C8<>"")+(D2:D8<>"")+(E2:E8<>"")>0)*(B2:B8<>"")*B2:B8)/SUMPRODUCT(--((C2:C8<>"")+(D2:D8<>"")+(E2:E8<>"")>0)*(B2:B8<>""))
If your first ID starts in A2, use this formula (edited to handle empty values in the "Rate" column):
=AVERAGE(IF(MMULT(LEN(C2:E8)*LEN(B2:B8),ROW(INDIRECT("1:"&COLUMNS($C$1:$E$1)))),B2:B8))
I have numeric data under fifty samples that are mostly similar. I want to count identical columns and give statistics on the same. There are too many rows to select them (37,888). Data looks like:
Sample 1 Sample 2 Sample 3 ........ Sample 50
4 4 0
4 4 0
4 4 ...
0 0
0 0
0 0
0 0
... ...
upto thousands of rows for each sample.
There is a column for date/time as well, would be nice if I could include that in the grouping.
In this snippet, there are many rows. Sample 1 and 2 are identical hence should be grouped together. Sample three would form another group and so on.
While I'm not sure what "There are too many rows to select them" means in this context (there is no limit on the number of rows or items that can be selected and included in a formula), this looks like a job for array formulas.
If you want to determine (for instance) whether columns C and D are equal, from rows 1 through 37888, you can use this formula:
=AND(C1:C37888=D1:D37888)
To make Excel treat this as an array formula, you need to press CTRL-SHIFT-ENTER (Windows) or CMD-ENTER (Mac) after typing the formula. The "AND" function will return TRUE if and only if all corresponding entries are equal: C1=D1, C2=D2, C3=D3, ..., C37888=D37888. It returns FALSE if any corresponding entries disagree.
Exactly what you do next will depend on the nature of the statistics that you want to compute for each group, but this formula will at least help you figure out which columns belong in the same group together.
I have a very long column( 50000 rows) and I want select a range (sample) of cells (number of rows) in order to apply certain calculations. You don't have to worry about the calculation formula. Here I just need help on how to do the sampling. The range(sample) should be changing based on window size. The window size is a number I can choose .i.e such in the example below I chose the window size to be 4. In other words, I need to have samples, and these samples are based on selected number of rows of the long column. The size(number of rows) for all of the samples will be equal to the window size. However, each sample is shifted by one from the main column. Now, the samples should be in seperate columns , and thats why I need to copy the selection in each sample in its required column.For illustration purpose, assume the below example:
let assume the window size( number of rows)=4
test
1
2
3
4
5
6
7
8
9
10
The expected output should be :
main col sample1 sample2 sample3 sample4 sample5 sample6
1 1 2 3 4 5 6
2 2 3 4 5 6 7
3 3 4 5 6 7 8
4 4 5 6 7 8 9
5
6
7
8
9
10
each sample of size 4 rows , however, each new sample shifs by 1 from the main column. Note we get 6 samples to cover the whole number of rows in the main column. What basically should be done: sample1 will be from row1-to-row4 from the main col. Now, sample2 will be 4 values, however, from row2-to-row5, from the main column. sample3 will be 4 values, from row3-to-row6, and so on until we cover the whole range of the main column. So there are two main process, selection and copy of selection.
I have tried to use the offset and other logical function ... but it didn't work. I don't want to use Macros or VBA... Is there are any built in functions to solve the problem.?
This is basically a variation of a range transpose. Use the formula:
=INDEX($A:$A,COLUMN()+ROW()-2,1)
Then just copy to whatever window size you want. It will automatically move down the main column by one row for every column over it is. The result looks like this (you are responsible for copying the formula to the right size):
Bonus, you can automate the column header "Sample N" with:
="Sample " & COLUMN()-1
