# List Of Random Numbers That AVERAGE A Predefined Number

Mar 13, 2007I want to create a long list of 10,000 random numbers between -100 and +150, but do it so that the average of all the random numbers equals 20.

I require a bit of code that locates where the excel file is stored - it then searches that directory folder for all file names. Any file names with an extension *.hm for example are listed in column A, while their relevant 'Dates of last Modification' are listed in Column B.

Every time the spreadsheet opens it should ask the user if he/she requires a re-search of this directory and update of any file names accordingly. NB: if a file name is deleted from the directory, the file name should remain in the spreadsheet.

I'm trying to create a staff rota which will populate a rota randomly when prompted - I have been trying to find some way of connecting the random lists and the staff names, though this has proved difficult (to say the least!). How best to proceed? I'm also fully aware of the possibility that my present design will also double book people (place then on reception and telephone duty simultaneously).

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 wanted to generate 11 random numbers between 1 and 10, which added up to 100 every time I pressed F9...

View 9 Replies View RelatedI have a frequency list (frequency per year) resulted from previous calculation. What I want is to generate random number as many as the frequency in the specified year, so that every year I will get the same amount of random numbers as the frequency. It is kind of the opposite of FREQUENCY function (but with random numbers involved). I need to use the result for further calculation.

I need excluding text from a cell and come out with a random number up to 3 numbers. Please see the attached image;

If you notice in column D there is text and a number that starts with a decimal, for example on the first row is .437 the next row is .215 next row is .63 etc... Is there a way to come out with a random number mixing it up to 3 digits and output those number on column "E"? Im only interested in filtering and coming out with the random number i mentioned .437 .215 .63 etc... not the +/-.010in.

There is no right or wrong number, i just need to come out with random number using up to 3 numbers up.

Maybe for .437 three numbers up could be .440 for the next row .215 maybe a number up .216..etc..

Hope there is a way to do this, my excel file is too long to type a number manually.

I vant to get a random number i a cell whenever my file is opened, but the random function is not working well for me as I always get the same number.

Sub Auto_Open()

MyValue = Int((99 - 1 + 1) * Rnd + 1) ' Generate random value between 1 and 99.

Range("A1").Select

Selection.Value = MyValue

End Sub

how to display the result i made in macro to active worksheet so that i can keep a record of the result made in my random generator,

Sub timer()

TextBox1 = ""

TextBox2 = ""

TextBox3 = ""

TextBox4 = ""

Dim x As String, i As Byte

Randomize

x = Format$(Int(Rnd * 1899) + 1, "0000")

For i = 1 To Len(x)

Me.Controls("TextBox" & i).Value = Mid$(x, i, 1)

Application.Wait Now + TimeValue("00:00:03")

Next

End Sub

Private Sub CommandButton1_Click()

timer

End Sub

Private Sub TextBox1_Change()

End Sub

I'm using the prob() function, and it works for no more than 61 random numbers. Does anyone know of a limit on the number of random numbers used in the function, and whether it's possible to use more numbers in the function? My formula is:

=PROB($C$11:$C$71,$L$11:$L$71,G11,H11)

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).

Say I have a list of 100 numbers (in column A). What formula would I use to have Excel list (in column B) 50 random numbers from the list of 100 or column A?

My objective is to take two different random counts of numbers written in column b, ranging from B9:B66. However I want to highlight the specific fields listed in the example below, and pull random numbers from those selected fields only. Then I want to pull another set of random numbers in the same column B9:B66, however using a different specific set of fields within column B; as shown in the second random formula string. Use the Press 9 feature to randomly select the two different numbers. What this attempt is trying accommplish is selecting one boy, one girl who have assigned numbers adjacent to their names(name field populated in column c).

What am I doing in correctly?

Hello, I have a column with 100 numbers in it. I want to be able to choose a number N and then calculate the average, minimum and maximum of the first N numbers in the list.

I have played around with countif and sumproduct but can't figure it. I don't know how index works, and wonder if that is the key.

Here is my formula that does not return accurate results:

=IFERROR(SUM(SUMIFS(Tenure!$H:$H,Tenure!$E:$E,{"=1100","=1090"},Tenure!$C:$C,{"=12","=14","=13"},Tenure!$G:$G,"=1/1/2013",""})/SUM(COUNTIFS(Tenure!$E:$E,{"=1100","=1090"},Tenure!$C:$C,{"=12","=14","=13"},Tenure!$G:$G,"=1/1/2013",""}))),0)

I need to average column H from the sheet Tenure IF column E is 1100 or 1090 (formatted as text) and IF column C is equal to 12, 13, or 14 and IF column G is less than or equal to a date and column I if greater than or equal to a date OR if this column is blank.

I tried AVERAGEIFS, the above route and many others. For whatever reason, I have been unsuccessful, but close many times.

I've seen a lot of traffic around running macro's on a clock at regular intervals. But what if I want to run a Macro (Macro1) at 8:55, 9:55, 11:55, 12:55, 13:55, 16:55 and another Macro (Macro2) at the top of each of those hours? The string of times is not consecutive, so I have built a table to define the release times. At each of these times I need to run a macros, and I'm not sure where to begin.

View 3 Replies View RelatedSo we had a month long, company paid (woohoo!) "weight watchers" challenge. On 1 worksheet ("Stats"), I have the Name of every Employee (A Column), then their Start Weight (B Column), End Weight (C Column), Department (D Column) and finally Location (E Column).

I know how sensative some people can be about their weight, so I locked the page and created another worksheet named "UI", which will display the "Average End Weight" for each department. So Human Resources would be the department in cell A2 on the UI sheet, with City 1 being the Column Header in cell B1. There are 8 cities (offices) and 23 departments.

So, for cell B2, I want to scan through the "Stats" worksheet and locate all of the cells in the department and location columns that read "Human Resources" and "City 1" respectively. Then grab the "End Weight" for every row that meets these 2 criteria, add them up, and divide by the number of "End Weights" that were grabbed.

My solution would be to make a separate column for each department (and then each city, so essentially 8 columns to represent all the cities for each department), use a nested (maybe 4) IF statements to then list only the end weight if that particular row meets the criteria, then at the bottom of each separate column, add all the shown numbers up and divide, then draw the information from THAT number into the "Average" cell on the UI worksheet. But it isn't very dynamic and if i want to use this sheet next year, there will be more employee info to be added and it would be a mess..further more, it would be...what...23 Departments x 8 Cities x 155 employees = ~28,500 added cells.

I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.

View 2 Replies View RelatedMy wife is a teacher and she has asked me if there was a way of randomly selecting a child's name from a pre-defind list and for that child not to be selected again during that session.

Some criteria:

Up to 35 children in the class (selected from a pre-defind list)A child can only by picked on once during the lessonA method needs to be in place for seelcting the child's name (either a button that can be pressed, or another option).

I sent this before but the formula I was given wasn't correct (as you will see from the file). In Column B of the second sheet (Data) of the attached file, I want to bring back the relevant name form the first sheet (List), which involves searching through the long descriptions from column A on the Data sheet for the name on the List sheet.

View 2 Replies View RelatedExcel 2003: I need code that, when an "x" is entered in a cell in the "Activity" worksheet to assign a temporary unit #, it will look for the next available Temporary Unit # in the "Assign" worksheet. Then mark that unit # as "assigned" (by placing an "X" in the column next to it) and copy it to a cell in the "Activity" sheet.

I will be doing the same thing with assigning different types of PO numbers. I figure if I have the code for the Unit #, I can use the same logic for the other assignments, with some modifications, of course.

I've attached a sample workbook.

If I am not considering the most effective way to accomplish what I am trying to do here, I have no ego at all about someone suggesting a better solution.

I have 25 random numbers and I would like to get a possible 5 digit combinations of these numbers. Can anybody help me with the possible formula?

View 9 Replies View RelatedE11 through E24 contains numbers and a few errors (#N/A) that need to persist (the errors need to show).

E10 needs to show the average of the numbers that are in E11 through E24, and just ignore the errors.

I have many columns like that - where the errors need to show and I need to show an average of the number/values that do appear, ignoring the errors.

How I could get an average of a 12 number list while at the same time removing the highest and lowest numbers. They aren't in any order either.

I'm doing the website for my company and things have to be entered into the site via spreadsheets. I have a list of numbers

e.g. 3652, 2845, 50925, 4809, 18392

that need to have the spaces removed in order for them to work.

e.g. 3652,2845,50925,4809,18392

There are over 500 cells with multiple numbers in each, so I don't want to do it one at a time, and rightly so, because Excel keeps changing the format and giving me something like

3.6*10^30 and loses all my commas.

Is there an easier way?

I need a formula that will add .1, .2, .3, etc. to a repeating list number. See the example below.

I am looking for a way to create a random order of numbers in a given range. For example, A1:a100 to be populated with a random number between 1 and 100, but not to duplicate, using every possible number within that range. I use the RANDBETWEEN function to generate the numbers, but I cannot prvent them from duplicating.
