Hi,
I have a serie of values (cf. bellow) from which I want to sort as following:
The coefficient of variation (CV) (=Stdev/mean) of this population should be 5% or bellow. As you might see from the whole population, the CV is higher than 5%. How can I keep the population the biggest possible with a CV of 5% or less and exclude the values which increase the CV above 5%. Is there a formula I could apply ? Thereafter, it could be nice if the excluded cells would automatically be detectable. Thanks for your help, regards, Tonio.

Hi, I am complete beginner to excel 2007 so excuse me if this question is obvious. I can not figure out how to find the range, coefficient of variation, and interquartile range using a set of numbers. Even if someone can point me in the right directions I would appreciate it.
Thanks.
What is the formula for "coefficient of variation", CV?

Hello, I am trying to figure out how to calculate the coefficient of variation in excel but cant figure it out. Any help would be appreciated.
Stocks Expected Return Probability of Occurring
-20% .20
-10% .25
25% .40
35% .15
That is the problem, what formula can i use to get the coefficient of variation.
Thanks
I have a data set based on an uneven distribution of cards in a 60 card deck, each with a value ranging from 0-5.
I need to build a probability distribution of all the random samples of 10. So, how many random sets of 10. have an average value of 1 (or a total of 10) etc.
Then, I need to build a variable distribution so that it changes as I change the sample size. So, with a sample of 20 cards, what does the distribution look like?
Can this be done in excel? Should I post what I have now to work with?
Hi everyone, first thanks for the help.
I am trying to create a histogram and let me explain some of the data.
I have a list of data separated like so:
3.5
3.6
3.8
3.8
3.9
3.9
etc...
Now I need to calculate the frequencies of these like so:
3.5 (up to but not including) 4.0
4.0 (up to but not including) 4.5
I can count out the frequencies myself but i need to create a histogram (bar graph) with the y axis as the frequency and the x axis as the IMR(infant mortality rate: ie the 3.5 (up to but not including) 4.0).
I am having problems with calculating the frequencies because when setting the bin values because they include 4.0.
If this is confusing I can provide some more information, but cannot find a good tutorial that would create a histogram anywhere remotely close to the histogram i drew by hand.
Hi Lords and Ladies!
I was wondering if there are any statistical tools in excel?
What I need is a comparison program to do the following:
Column A: abcdefgh
Column B: bcaghfrnreo
Column C: 80% match (roughly)
Is that possible to do in excel?

I am having difficulty setting up a Excel sheet for the following problem.
An industrial Engineer at ABC Products wants to determine whether there are more units produced on PM shift then AM Shift.
Sample of 54 Am workesr with a mean number of units produced is 345 with a standard deviation of 21.
Sample of 60 PM workser with a mean number of units produced is 351 with a standard deviation of 28 units.
Significance level is .05
Trying to figure out if the PM shift is larger.
Morning All,
Does anyone know of a free tutorial that can explain how to get statistical data in Excel? - I have seen it done before (in excel) for 'Linear regression', I am wondering if the same can be done for "Polynomal"?
