I have a file (see SAMPLE file attached) with over 2000 records. I need to know if there is a way to do a sampling or random selection by ethnicity and gender in order to get a diverse population for only 60 individuals. The selection criteria should be on ethinicity and gender.
Is this possible?
I'm trying to take a random sample without replacement. The sample is also partially representative, e.g. if a certain proportion of the data are Class A and a certain proportion is Class B, that proportion is maintained in the sample. After the proportions are set, the observations within each class are randomized.
Is there anyway to sample a number of rows, where the number of rows is based on the value in another cell, without having to use a lookup function or index match? Sorry if the question is a little unclear; please let me know if you need any clarification.
I have data for number of firms as :

how can one chose random samlpe from this population.
random number selection...
i have a list of 200 items (rows) and i would like to "randomly" select 30 of them...(next month i will get another 200...)
I'm trying to select an x number of random selections within the selection.
Basically, lets say A1:A100 is selected, im going to have a inputbox asking how many to select, you put 10 in the inputbox, and then it randomly chooses 10 from A1:A100 and highlights them
This seems easy enough, i can do the input box and know the random function. just not sure how to set the beginning point and the ending point with Cell locations and then have it highlight those selections... a for loop I'm guessing?
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, _

View 6 Replies View Relatedorganising a golf tour for 32 players.playing in teams of 4 (4 Balls) for 4 games of golf and the teams are to be randomly selected such that no player plays in a group with a person he has played with in a previous game. finding it difficult to create a spreadsheet which meets this criteria.
need to build into the spreadsheet the fact that the variable mix of people is constrained by the fact that at least 4 persons have to use a buggy (which will have 2 people in it) and as the tour progresses and courses become physically demanding a number of people (N) for the last 2 rounds may also ask for the use of buggies as well.develop a spreadsheet to make the 4 Ball team selections.
I 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?

I am wondering, in excel 2003 is it possible to randomly select two numbers from one column, say column b9:b45, that are random numbers, and selected by two different font colors. In other words: b9=1348, b10=1349, b11=1350, b12=1351, b13=1352, b14=1353.
Say we press a macro button, and in field B50 one radom black colored number is selected of a field of say 30 numbers that are all black in that column, and in b51, one red number is selected, in a field of 30 red numbers. We want to used this macro to select winners simulating a raffle drawing.
I have a list similar to the below:

7Emiliano Bigica 13
8Julio Baldivieso 12
9Fabrizio Miccoli 13
10Peter Vougt 14
11Massimiliano Esposito 12
What I want to do is randomly select either number 1 to 11 (leftmost column OR the person it represents) but also make the selection based on the percentages in the rightmost column. To illustrate using the above example, Number 11 (Massimiliano Esposito) should have 12 times more chance of being randomly selected than Number 1 (Artur Boruc)...
I have used a formula such as
PHP
=INDEX(A$1:A$11,INT((RAND()*11)+1),1)
to randomly select a cell but how would I modify this to include cell weightings? Or is there a better formula?
An additional note I have is that the weighting for each person will always be changing, but will always be a percentage.

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 1 Replies View RelatedI tried very hard to design a leave roster for user to mark their leave application. The criteria are as follows:
1. 4 applications per date
2. a region of worksheet (i.e. "A2 to H20) will be defined for users to "click" on the cells (within the defined region) to mark their application.
3. once a cell is clicked (i.e. marked), it cannot be altered.
4. each click will automatically increase the total by 1.

I have attached a portion of an excel file I am using at the moment. What I require is a piece of VBA code which will allow me to copy selected data based on a combo box selection. What needs to happen is this :-
If the selection in the "Index" worksheet combo box related to "Month" in cell G19 is for instance "December", I would like the macro to compare this cell value to the cell values in cells C96, C124, C152, C180, C209, C236, C263 and C290 in the "Tech Services" worksheet and where the values match.......copy the commentary (Range C126:Z147 in December's case) to the range C34:Z55.
I am working on a project where user has to select an item from a listbox, however there is a condition that if user select an item, other items of listbox should be disabled so that he/she can not select any other item.

and
VB : Listbox.locket = True

I want to have a drop down list in a cell so that the value in the cell can be only selected from two columns of data. Additionally once the data from the first column has been selected I want to be able to limit the inputs the user can select from in the second column.
e.g. In cell C115 I want to have the value BDS05.
I want to be able to select the value BDS from a drop down list of values and once that value has been selected I want to be able select 05 from a list of values from 01 to 14
If I select BCS as the first value then I want the second set of values to be limited to 01 to 02 etc.
I have read about combo boxes and list boxes and I'm a bit confused about the best way to achieve this (or even if I can).
I'm using the following code in a worksheet:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
col = ActiveCell.Column
Range("output") = ActiveCell.Offset(0, -(col - 4)).Value
End Sub
In case it's not obvious, the macro places the value in the active row and 4th column of the worksheet into the range "output".
The problem is, the worksheet is large and somewhat slow to recalculate. This macro forces a recalc on any selection change, but i only need it to run when the row selection changes, not the column.
I'm sure there's a straightforward way to reprogram this.
I'm trying to build an investment calculator. Tried searching "calculator" as keyword but return nothing similiar.
There are eight cell : [ A ][ B ][ C ][ D ][ E ][ F ][ G ][h]
[ H ] is price of the leverage
[A] is X balance
[b] is X lot size
[C] is X amount of money use to get x lot
[D] is X percentage of money use to get x lot
[E] is X point gain
[f] is X money gain
[G] is balance + money gain
Ignore the formulae for leverage to determine 1 lot price. Take 1 lot = 250.
What I'm looking for is when I enter any value at cell B, C or D, it will automatically calculate the value for either B, C or D cell.
Let say, the balance is 10000.
If I enter 2 at cell B. Then, it will calculate the value for cell C & D.
If I enter 750 at cell C, then it will calculate value for cell B & D.
If I enter 25 at cell D, it will calculate value for cell B & C.
