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))))))
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.

Nov 17, 2006I want to calculate the standard deviation of a whole population in my database (total population: 36,458)
I used the STDEV equation however, I went into help and it says that the equation calculates STDEV based on a sample of 30.
I don't want to calculate a standard deviation based on a sample. I want a standard deviation based on the whole population. Is it still okay to use the equation?
The reason I want to calculate the standard deviation is so that I can use that number to calculate the sample size needed for my population so I can create a histogram.
Calculate The Quantity Of Each Size Of An Item
Nov 26, 2008I need a formula that will calculate the quantity of each size of an item (XS,S,M,L,XL). For example to calculate the quantity for Mediums, I need the formula to look at column C, if M is entered, then look at the adjacent cell in column A for the quantity and formulate a total number (from rows 4-21) and enter the total quantity in C27. See attachment.

Oct 22, 2009Ok, so this is my first attempt at an excel macro. I'm trying to develop a macro that will assist me in auto-populating a column in a new worksheet based on another worksheet. Recently I ran a new report at work that is 4000 lines long that I really do not want to have to edit by hand, since I already had to do it with the older one.
I can't post my data but i'll try to explain it the best I can, but basically it's set up as a part number, next column is the steps in completing that part, and then a workcenter number. I'm trying to populate that workcenter column in the new worksheet. I've put this macro together with the best of my ability along with excel help and the internet but I just can't seem to get it to work.
Divide Population Into Deciles
Jun 15, 2009Excel has a QUARTILE function to divide a population into quartiles. I'm trying to do something similar but divide a population into deciles (i.e., every 10%). Is there any easy way to divide a large population into deciles and to assign a decile to each value in the population (i.e., top 10%, 11-20%, 21-30%, . . . bottom 10%)?

Weighted Average Formula Population
Jul 13, 2007See attached picture. This shows Profit and Growth for the stores in each region.
The percentage total is weighted based on the profit of each store in the region.
What I have is an excel sheet with hundreds of regions (going down), all with a different amount of stores. I need a way to populate each of its Region % Total with the weighted average formula (in my example, cells C8, C12, and C20) while also varying the formula to include only the stores in the region.
For example, C8 calculates the weighted average for %s in rows 2 through 7 (6 stores), but C12 calculates it for rows 9 through 11 (3 stores). I need the formula to vary based on the number of stores.

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.
List Box- Sheet With The Following Sample Data On It
Dec 5, 2009I have an excel sheet with the following sample data on it.
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.

Random 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.
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?
Pull Out The Sample Date And Time 20 Times
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.

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.
