Hi,
I was hoping someone could help me with this particular statistics+excel problem that I cannot solve, or, at least need some confirmation that I am solving it correctly...
MY DILEMMA: Let's say I am asking people to choose their favorite letter(s) ranging from a-vvv (1-100). I ask 9 people to choose their favorites, but they can't choose more than 100 #'s (obviously since a-vvv represents 100 letters). Once I gather the information, the only way I know how to create the proper order is to AVERAGE the data by inputting zero into the fields/letters that were not chosen (since no one chose all 100 letters). My question is... HOW DO I PROPERLY ORDER THE "LETTERS" FROM MOST TO LEAST POPULAR BASED ON THE SUBMISSIONS??? I realize this is a statistics problem, but I'm hoping something efficient can be done in excel.
I've also attached the working excel file to use as a working document. Feel free to PM if you would like to attach an excel file.
Thanks in advance everyone!

hiya all i was wndering if anyone could help me i need to work the probability of number using a percentage for expample 50 sales has a probability of occuring 40% and 60 sales has probability of occuring 5% and so on, can any explain how i need to do this im new to excel ,
thank u
I have a pack of cards and already drawn some cards.
I have 40 cards left: 12 diamonds, 11 hearts, 10 spades and 7 clubs.
The probability of the next 3 cards being (in order) a diamond followed by a club then another diamond is (12/40)*(7/39) * (11/38).
The answer is 1.5587%. What formula should I or could I use to get this result? I'd imagine it would be a nested formula that's not going to be easy to decipher!!
My problems I'm encountering when trying to get Excel to work out the probability for me without me having to hard-wire the figures in to the formula:
The cards are not being replaced, so when a diamond is drawn out, there is one less diamond in the pack to take into consideration when looking for another diamond. It's easy when, say, there are the same number of each suit left remaining but this is not the case!!
I can see a long-haul solution would be to list every possibility then lookup the desired combination but time/speed/hassle.... there's another easier way, isn't there?
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"?

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.
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 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 all, my first post so i hope you can help!
I have some data for quotes a company has been sent, with a number of variables, for example qty of items requested, value of quote, length of time it took to return quote etc... And finally a yes or a no column as to whether the business was won.
What i want to do, but i'm having touble getting head around how, is produce some sort of table of probability for success of a quote.
For example, if a quote comes in for 50 items, and we return the price within 20 days, what is out chance of winning the bid?
Any ideas, do i need multiple tables for each variable with a yes or no against each, then compare these, or is there some fancy statiscal test i can do?
Any ideas?
Thanks,
