how to use the random number generator to generate unique numbers (1-55) based on the odd percentages in the attached chart.
for example in the chart, chances 1 through 10 are more likely to be generate first rather then the last chance number 55 based on the draft pick odds....
In my worksheet in column CC in C1:C20 I want Excel to ganerate 20 random numbers between 1 and 80 without repeating the same numbers.
At present I have the following formula entered and it works, but after I click F9 some repeated numbers are generated.
=INT(RAND()*(80-1)+1)
How can I change the formula or replace it?
Is there a way to control the number generation. I would like to be able to run different scenarios with the same set of random numbers, then regenerate the random numbers and do it again. Right now every time I do anything in the spreadsheet, I get a new set of numbers.
View 4 Replies View RelatedI have developed some VBA code which produces a 'lucky number' using the RND function. The final number is produced by concatenating three individually generated random numbers between zero and 9. When the code is written in a Module, I can display each number as it is generated, by 'pausing' the macro with a For Next loop.
I have now developed a similar application using a MultiPage Userform, but the individual numbers are not displayed when I use exactly the same code. The only way I have found to display each number as it is generated is to use
Application.Wait
However the shortest wait time seems to be 1 second, which is too long. I would like to be able to make the MultiPage version look like the Module version.
I attach a workbook which shows both of the above.
Is there a way to auto generate a unique number that will stay with the adjacent data record? My problem at the moment is when a record is deleted or the data sorted the ref number changes. I am using Excel 2008
View 6 Replies View RelatedWhat I need to accomplish here is to randomly (or at least seemingly enough) generate a number between A and B values for many cells.
I know i can accomplish this through =Rand()*(B-A)+A
However lets say that the lower limit is 96 and the upper is 100. How would i get my data spread to appear to center more around 98-99, with a few randomly placed a little farther out but still within 96-100? I'll say i have 500 instances of this generated number. So what i need is the appearance that most of the numbers lie within the inner range with some anomalies outside that but still within the greater range, having fewer and fewer instances as the value gets closer to the outer limits.
I'm also placing this value in cells using VBA (most likely "for each cell in range(xxx)...")
How would i go about this?

I am trying to highlight a cell based on two randomly generated number, one is the column and the other is the row. Based on those values I want to change the color of a cell in a range of data. The formula I am using does not work like I intended. It only changes the cell once I enter a value in the cell not until. =OFFSET(A1,B27,B26). B26 and B27 are the cells housing the random numbers and A1 is the base reference.
View 1 Replies View Related I have been able to put together the below which generates a random 15% sample of all records in the worksheet.
It works perfectly, however what I would ideally like to do is get it to only produce the 15% sample of rows where it is todays date in col B and has the word "other" in col C. I've tried lots of different IF statements and FOR statements, but am only generating blank worksheets.
Sub getrandomrows()
Dim lr As Long, lc As Integer, a As Variant, MyDate As Date
lr = Cells.Find("*", LookIn:=xlValues, after:=[a1], searchorder:=xlByRows, _

I am working on a challenging project. I have a list of names, job titles, and departments. Is it possible to select a random name who matches a specified job title or department? I'd prefer not to sort/filter/delete the original data range because the sheet will be used multiple times during the day by multiple users and with different criteria each time.
View 6 Replies View RelatedI want to do is randomly pull from a field of data, MINUS any cells that do not meet the criteria in other columns. So if column A is my target column for the random selection (containing 10 unique entries), and column B has 10 repeating colors, and column C has 10 repeating animals, what can I use to perhaps create this effect: A random pull from column A, but only from rows in which column B says red and column C says cat? (The pull being 1, 4, 7, or 9 in the below example, of course.)
Data (this example is also attached in an excel doc):
One Red Cat
Two White Dog
Three Blue Horse
Four Red Cat
Five White Cat
Six Blue Cat
Seven Red Cat
Eight Red Dog
Nine Red Cat
Ten Red Horse
I have tried variations on IF and INDEX to no avail. Perhaps something with SUMPRODUCT?
How do I make a row of 5 random numbers in A2:A6 that are not the same as each other. It's basically for a Bingo card. I have a formula that can calculate the random numbers =INT(RAND()*15)+1 under the B's for example, but I can't seem to figure out how to make it so they are not the same.
How can I make sure that I can generate random numbers that don't repeat using the rnd function in VBA.
View 14 Replies View RelatedI have build a system that needs a lot of random numbers generated to work.
I have used what I thought would work to generate me these numbers like this example:
VB:
Lastrow = ThisWorkbook.Sheets("RPlay").Range("A" & Rows.Count).End(xlUp).Row
RPlayerNum = Int((Lastrow - 2 + 1) * Rnd + 2)
This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.
However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.

I get the following error whenever I try running a Monte Carlo simulation with iterations in excess of 64000 (The MC simulation calls the 'NormSInv' worksheet function at least once per iteration, and the argument to the 'NormSInv' function is always a standard normal RANDOM number also generated by Excel VBA): Run-time error '1004': Unable to get the NormSInv property of the WorksheetFunction class
Why do I inevitably encounter this error ONLY when the number of iterations exceeds 64000, for instance? Simulations with iterations < 64000 run smoothly without a glitch.
I am using the data analysis add-in to generate a random number (using the random number generation) using a normal distribution. The problem is, i want it to recalculate these numbers every time the worksheet is recalculated but the numbers seem to be values only.
View 2 Replies View Relatedi have worked in access using vba procedures. i can easily create a form in access that generates a random integer number between 0 and 20 and the user will guess the number between 1 to 20 if the random number is 16 and the user enters 14 the program will display a msg box saying too low or too high. here is the code .
Option Explicit
Private Const MAX = 20
Private Const MIN = 1
Private iKey As Integer

I understand how RAND and RANDBETWEEN work, but have a slightly more complicated random number generation problem that requires a number that isn't solely between two numbers.
I have one cell that is randomly generating a number between 0 and 350 (we'll call this value A) and another randomly generating a number between 0 and 15 (value B). Then, I have a third cell (value C) that equals 15 minus B. Where I am having trouble is with a fourth cell (value D). This cell I want to have randomly generate a number between 0 and 350 but it needs to be D less than the value in A or C more than the value in A. Is there an advanced random number generation technique that can solve this?
I have a spreadsheet of 1000+ companies and I want to take a random sampling of 100 of them. I would assume this could be accomplished by auto-filling a numerical value to each line of data (which I did), then scrambling only the column with the numbers (which I can't figure out), and then selecting the entire text and resorting it to put the numbers back in order and then just work with the first 100 rows (which I can do, if I knew how to make the numbers random).
