View 2 Replies View RelatedRandom Sample Out Rows Of Data From A Sheet
Oct 4, 2009I've coded a macro that can randomly sample out rows of data from a sheet. This macro is used to sample out certain rows from a master sheet full of data (which has 48 columns) based on user names (a column titled LAST_UPDATE_NAME). For Example (ref. wkb attached), if for 5 users named Alastor, Catherine, Emma, Julie and Victor for whom i've to choose data from the Dump sheet.
I need to design a module in which if i input the no. of samples to be chosen against each name, then that many number of rows has to be chosen for that particular name and copied to a new sheet (probably such sheets can be renamed with the usernames). Also i want to consolidate the copied data from the multiple sheets and consolidate them to one sheet.
Random Sample Of Size N From Dynamic List
Feb 13, 2014I am working on a sampling tool in Excel which is based on what a user enters into a column. The user enters observation codes (text) in column A beginning at row 2 and going down to however many they have. I already have formulas which determine the sample size needed based on the number of nonblank values in that column; the resulting sample size is in G4. I'm thinking that I will need to have a form with a button module to select the random sample from the values in col A. This way Excel isn't running the module while the user is entering the values. The resulting sample can be pasted into a separate column or sheet.

Dec 3, 2009I have a file that samples performance on a cpu. The output shows the sampling date and time in column A. This column changes depending on how long I run the file. No matter how long the column, I only want to pull out the sample date and time 20 times. So if I had data in column A with 300 rows, I want to divide 300 by 20 and pull those 20 numbers and put them in column B in chronological order. Same thing if I had 4000 rows in column A, I only want 20 samples.

View 5 Replies View RelatedExcel 2007 :: Differentiate Between Sample IDs
Apr 24, 2013I am working in excel 2007. I have been using the COUNTIFS function to pull out some summary stats from my data. For my data I have sample ID's which are a letter followed by a number e.g. A12, A20, A39, A50. I have 40 columns of variables I am looking at which for each sample ID have either a value of 0 or a numerical number. For each column, I want to count firstly any samples that are greater than 0 (i.e. they have a numerical value) AND if the sample ID differs. This is because I have multiple samples per ID and so I want to know how many different ID's have a numerical value.
Is this at all possible in Excel? I do not know all of the functions very well, so I cannot find anything that will allow me to look at differences in the samples ID.
Average Formula When Sample Size Changes
Jan 17, 2008I am computing the average of anywhere from 5-10 numbers. When the numbers are not inserted there is nothing left in the cell. The problem is I get a value that is close to the average but not the real average. (Also the cells I am using are N37:Q41 for the first 5 samples which is constant the next 5 are not always constant W37:Z41) Here is the formula I am using:
=IF((W37="")+(W38="")+(W39="")+(W40="")+(W41=""),AVERAGE(N37:Q41),IF((W38="")+(W39="")+(W40="")+(W41=""),AVERAGE(N37:Q41,W37),IF((W39="")+(W40="")+(W41=""),AVERAGE(N37:Q41,W37:Z38),IF((W40="")+(W41=""),AVERAGE(N37:Q41,W37:Z39),IF(W41="",AVERAGE(N37:Q41,W37:Z40),AVERAGE(N37:Q41,W37:Z41))))))
I have the same problem with a standard deviation formula and the same group of numbers (I get something close but a few points off).
=IF((W37="")+(W38="")+(W39="")+(W40="")+(W41=""),STDEV(N37:Q41),IF((W38="")+(W39="")+(W40="")+(W41=""),STDEV(N37:Q41,W37),IF((W39="")+(W40="")+(W41=""),STDEV(N37:Q41,W37:Z38),IF((W40="")+(W41=""),STDEV(N37:Q41,W37:Z39),IF(W41="",STDEV(N37:Q41,W37:Z40),STDEV(N37:Q41,W37:Z41))))))

Name Age Sex Height
Ray 33 M 5' 8''
Sind 29 F 5'4''
Ralph 3 M 2' 1"
Ryan 1 M 1' 2"
I have managed to extract this info onto a form named Form1 which has 4 list boxes in which the above info is displayed in the same format.
To be more precise
Listbox1 shows all the Names,
Listbox2 shows Age
List box3 shows Sex and
Listbox4 shows height respectively.
What i want to do is, When i select an item on Listbox1, all corresponding enteries on Listbox2, 3 and 4 should also be simultaneously highlighted,
For example if I select the third data Ralph on the ListBox1, then ListBox2 should highlight 3,
Listbox3 should highlight M and
Listbox4 should highlight 2' 1" simultaneously.

Randomly Choose Sample Rows After Using Autofilter
Nov 5, 2009Can anyone explain clearly (using layman terms) about how to go about randomly choosing specific number of rows from a set of autofiltered records?
For e.g., If there are 1000 rows of data in a worksheet and after applying autofilter to certain column(s) [one or more] say i get some 75 rows. Then how can x no. of rows be chosen where x can be input by the user or calculated based on a certain percentage? Say if out of these 75 filtered rows, 8 rows have to be chosen randomly - where 8 can be input by the user or also be calculated as 10% of 75.
Also, is it possible to choose these x records from the filtered set of rows without actually copying them to another sheet?

Extraction Sample Of Emails From A Sheet Proportionate To The Original
Nov 10, 2009I have been set a task to do and I wonder if you could point me in the right direction.
Task - extract 2000 emails from a 6000 email database
The 2000 emails have to be proportionate to the original database.
e.g.
The main database has the emails plus town and employee size ranges
Column A - Emails Column B - Town Column C - Employees
So if Column B states that 50% of the entire database is from one town, then my extracted emails must also have half from that town (1000).
Also there are around 5 employee ranges and so they need to also be proportionate to those percentages too in the final extraction.
Display Cell B1 Value In Sheet1 Of All Workbooks In Sample Workbook
Feb 24, 2014I have a workbook name Sample and I want the code to run when its opened and it should check the first sheet "Sheet1" in all the workbooks in the folder C:FolderTemp.
And if the first sheet name is not "Sheet1" then just ignore that workbook and move to next workbooks. If the first sheet name is "Sheet1" in a workbook then store the value present in cell B1 in Sample workbook "Sheet1".
So if there are 5 workbooks in the folder C:FolderTemp and two of them hasn't got first sheet named "Sheet1" then display value of B1 in rest of the 3 sheets to the "Sheet1" of "Sample workbook" one after another.

This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.

View 3 Replies View RelatedVBA Random Name Select
Dec 12, 2012I have been thinking about a name selection tool that would automatically pick a few names for internal audit. I can handle the useform launch and other basics but here is what I see happening.
1. The empname! sheet contains a list of all the company employees, with employee number in column A, names in column B and an "X" or blank in column C.
2. The main sheet called auditmaster! contains nothing currently
3. When the code is ran the userform prompts the user to select how many individuals to audit by entering an integer in a textbox.
4. If the user selects 5 for instance, the code will run and will select 5 random employees for internal audit. It does this by first checking column A of the empname! sheet and seeing what the highest and lowest numbers are. This would create the range for the random function.
Next if there is an "X" in column C of empname! sheet, those employees numbers are excluded from the random choice.
Following this the function will select the appropriate number of individuals to audit using random again and place their names/number on the masteraudit! sheet.
The detail should be placed as the following, employee number goes to column F, name to column G. Starting with row 10. The code should also number the results 1 - however many were selected for audit in column E.
