How To Calculate Even Distribution Between Two Values Over A Set Number Of Columns
Feb 17, 2014
I am in need of a formula to calculate the even distribution of values between two set values over a set number of columns. For example take a look at the attached screenshot. I have the numbers 2.88 and 2.44 and I need to fill in the empty cells between the two with with an even distribution of numbers in between the two (in descending order) over the 8 columns Screen-shot-2014-02-16-at-3.33.08-PM.jpg

I have weird alpha value like 14.385%, a sample size (36). What is the corresponding critical value for the normal distribution. There are questions like this dealing with the Student T dist, Chi Squared and F distribution. If i can figure out how to do it for one I can probably do it for all of them.

in VBA the RND function generates a random number using uniform distribution (every number is as likely as any other). Is there a function to generate a random number using normal distribution where the numbers closest to the mean are more likely to occure then numbers further away from the mean. I've created the following custom function to generate a random number between two given values using uniform distribution.
Function RandNum(Min As Double, Max As Double) As Double
RandNum = (Max - Min) * Rnd + Min
End Function

I don't know anything about the distribution functions, but I have a range of numbers and I need to know each number's rank within the range. I believe that's related to distribution, so if someone could tell me how to go about calculating that (with or without those particular functions)

I've managed to write a random number generator that produces multiple sets with no repeating numbers per a set.
Now, to step it up a notch, I'm trying to create an even distribution of the numbers generated which is where I could use a hand. Here's my current code:
Code:
Option Base 1
Sub RandomNumberStrings()
Dim rndno As String, strg As String, msg1 As String
Dim r1() As String, r2() As String
[Code]....
Equaling 500 numbers generated as intended, but my target is to get every number with an equal frequency.

how to go about generating random numbers based on Weibull distribution in VBA? I had a rough idea for Normal (from link below) which i later extended to Lognormal but am having difficulty with Weibull and Gamma will appreciate any help.

I would like to get random number generator for normal distribution and I’m using:
=NORMINV(RAND(),$B$1,$B$2)
Where B1 is mean (average) and B2 is SD.
This command works, but in the random generating numbers, I’m getting positive and negative numbers (ex. -23,34).
how to change command so I can generate positive only numbers?

My spreadsheet is set up so that Column A has dates and Column B has a value. How can I calculate the total number of values for each day of the week? I've tried a few formulas but they either didn't work or didn't actually take the value into consideration and just counted all the 'Mondays'. I'm not sure if that's clear enough, but if we're just looking at Mondays to simplify it:
Monday, 1 January 2000: 2
Monday, 8 January 2000: 5
Monday, 15 January 2000: 0
Mondays: 7

I have 2 Columns of Holiday Dates (Column A is the "FROM" date; and Column B is the 'TO' date) and Column C is Peoples Names corresponding to the Holiday dates:
ie:
COLUMN 1 ; COLUMN 2 ; COLUMN 3
A1= 2 Jan 13 ; B1= 10 Jan 13 ; C1= Tom
A2= 4 May 13 ; B2= 10 Jun 13 ; C2= John
A3= 7 Jul 13 ; B3= 10 Jul 13 ; C3= Tom
A4= 3 Aug 13 ; B4= 25 Aug 13 ; C4= John
A5= 6 Dec 13 ; B5= 15 Dec 13 ; C5= John.
I am trying to figure out a formula (eg SUMIF) to calculate and summarize the number of Days Holiday based on a person's name (eg Tom's total Number of days Holiday days) based on the above column configuration of Dates and Names.

I have a file with a column containing a series of records where a reference number can be repeated several times. I want to create a formula that will count the number of unique reference numbers in the column.
However - and this is the tricky part - I need it to allow for when the report is filtered, i.e. something like a SUBTOTAL function which ignores the hidden values.
So, the column in the full report has 691 unique values across 2,200+ records. If I apply a filter the column only has say 78 unique values. Is there a formula that can calculate this?

I have 12 columns of data. In those 12 columns of data I have 3 digit numeric IDs. I want to count the unique number of IDs for each row. I have about 14K rows.
What would be the best way to do so?
Some rules about how the data is stored. I have 12 columns of data with anywhere from 1 to 12 columns having data for each respondent. Data always fills left to right and never skips columns.
I have attached an example file that represents how the data is stored and the output I would like (Unique Count).

My data comes from 3 different sources
Source A = 4 columns (3rd one is important)
Source B = 8 columns (3rd one is important)
Source C = 5 columns (4th one is important)
Is there a slick way to capture values based on the number of columns in that row?

I have several columns in an excel sheet which contain values (eg. Names). The entered names can be unique or already exist in the column. I need to find out (using a function or macro) how many different names were entered. Duplicates shshould be ignored in the count.

I have two Columns C and E that have dollar amounts in them. I want to compare each row in those columns and then total the number in column C that are higher that column E.
So basically C6>E6, C7<E7, C8=E8,C9>E9 should return the result of 2. There are two instances where the price in C is higher than the price in E.

I need a formula that will calucalte the monthly total based on the following conditions:
Col A = Yearly Cost
Col B = The number of the month when the costs are starting (1=Jan etc)
Col C = The duration or the number of months for which the costs are to spread
Col D is Year 2013 with the months across columns D-O. Row 1 above those columns shows the month's corresponding number.
Right now I have =IF($B3<=D$1,$A3/$C3,0) however if my start month is 1 and my duration is 5, I need the costs to stop after May. I've attached a sample file. Calculate based on start month and duration.xlsx

How to create a spreadsheet with what I think will be a very simple formula?
If date in B2 - date in A2 is 1 or less days, put a 1 in cell C2.
If date in B2 - date in A2 is 7 or less days but more than 1, put a 2 in cell C2.
If date in B2 - date in A2 is 30 or less days but more than 7, put a 3 in cell C2.
If date in B2 - date in A2 is 90 or less days but more than 30, put a 4 in cell C2.
If date in B2 - date in A2 is 91 days or more, put a 5 in cell C2.
OR
Another, maybe simpler, way of saying it is:
If date in B2 - date in A2 is 1 or less days, put a 1 in cell C2.
If date in B2 - date in A2 is 2-7 days, put a 2 in cell C2.
If date in B2 - date in A2 is 8-30 days, put a 3 in cell C2.
If date in B2 - date in A2 is 31-90 days, put a 4 in cell C2.
If date in B2 - date in A2 is 91 days or more, put a 5 in cell C2.

This is a piece of a spreadsheet meant to track patient Range of Motion performance over a max of 4 weeks. How do I calculate % Improvement [write the formula for column J] to account for the fact that sometimes a patient is discharged after being seen 2 weeks OR 3 weeks or 4 weeks. I don't want to change the formula every time.
The SUMMARY % Improvement in J7 - will be changed to the average of each individual patient % Improvement from column J.
Looks like I need a dynamic range from what I can see from Googling. Do I need to use Offset ?

REFER TO MY ATTACHMENT.
Can I get a simple ONE LINE formula to calculate the below combination
Basic Cost = 100 (A) (my Material cost)
ADD : 10% for Freight (B)
A+B = C
ADD : 10 % for Overheads on 110 (On C) = D
C+D = E
ADD : 15% towards Margin on 121 (on E) = F
E+F = G
WHERE G = 139.15
I require this because my %s varies according to products.

I know EXCEL has functions for both the NORMAL DISTRIBUTION and the
cumulative value thereof...
but is it possible to graph this data..
(I imagine if I sort the data and then calculate the ***. distributions into
a column...then chart it, it should work; BUT IS THERE ANOTHER WAY?)

I have been working on a problem that requires being able to calculate the chances of any winnng a series of coin tosses with a weighted coin.
The coin has for arguments sake a 65% / 35% chance of landing heads or tails and to win the game you need to hit your side 9 times.
Can you use excel to calculate things like: If heads takes the lead 1-0, what does that mean the its overall percentage chance of winning? If the score is 7-3 to tails, what are the chances of either side gaining victory? etc, etc.
I thought that there would be a way of setting up a spreadsheet that listed the goal (first to 9, 12, 15 or whatever) and below this the percentage chance of heads and the percentage chance of tails. Then somewhere would be a box to enter the current score (0-0, 3-5, 1-1 or whatever) and beside this the current chance of heads or tails gaining victory.
I've tried setting up something like this but am a bit of a dufus when it comes to knowing how, where and when to use the different functions of excel.

I'm looking to analyse is how long these articles take to reach maturity from their date of publication (so, when they achieve their optimum performance).
I'd then like to further analyse this across various metrics like article type/producer etc., which, I guess, would be in some kind of Pivot Table filter-type-thing.
Here's an example of some of my data:
ArticleName - PublishedDate - OctViews - NovViews - DecViews - ArticleType - Producer
Article1 - Oct-08 - 3701 - 4856 - 4561 - Food - ABCTV
Article2 - Nov-08 - 0 - 9824 - 1256 - Food - ABCTV
Article3 - Oct-08 - 1358 - 8953 - 9652 - Tech - XYZ.com
Article4 - Oct-08 - 1351 - 2354 - 3562 - Tech - ABCTV
The part I'm finding tricky is this; what we'd like to do is rather than look at a specific date (say, articles published on 09/04/08) it would be useful to combine all the dates so that the first month something is published is Month 1, regardless of the date it is actually published.
As the same article can be from the same producer but published at different times, if I could remove the "Jan-Mar = Month 1-Month 3" problem it would allow us to graph all the data into one snapshot of the publishing process and find trends. If this could then be cross examinable by the ArticleType etc. it'd be really useful.

I have a spreadsheet which has a list of staff (column B) and work categories (row 3).
Row 4 is updated each day with a count of the incoming work for each work category.
I want to be able to randomly distribute (as evenly as possible) the no of work items in Row 4 between the doers (B7:B13). Each item of work also has to be checked so I would also like to randomly distribute the checking between the checkers (B16:B18)....

Say I measure the height of 1000 people and I have those in a column in excel. It should be a normal distribution with mean x and standard deviation y. How do I actually graph it so I can see the normal distrubution curve that looks something like this:
[url]
I tried making a scatter graph but it graphs them point by point. I want the height to be on the x axis and something like frequency on the y axis.

There is trading system which generates a winning trade per ONE stock in ONE month’s time with a probability of 5/12 (0,4166%). If the system trades 10 independent stocks the probability of any number of winning trades occurring out of all of them in ONE month is shown below:
None 0,0046
One 0,0326
Two 0,1047
Three 0,1995
Four 0,2494
Five 0,2172
Six 0,1272
Seven 0,0519
Eight 0,0139
Nine 0,0022
Ten 0,0002
I took these values from a book…I tried to reproduce these values in the spreadsheet that I attached. My table looks as follows:
0 0,0046
1 0,0033
2 0,0023
3 0,0017
4 0,0012
5 0,0008
6 0,0006..........
