Analyzing data - what tools should I use?

I am analyzing data of seat distribution among different types of rail wagons. I have m types of wagons and n seats. What I want to achieve...Hello,

I am analyzing data of seat distribution among different types of rail wagons. I have m types of wagons and n seats. What I want to achieve is to find the sets M of m and N of n where M.N->max. And in addition, which is the most important, I need to know exactly which are the objects in the sets - the wagons in M and the seats in N.

I have uploaded an excel table with information about the seats and the wagons. You have the seat number in the first column and the wagon types in the first row. The content of the table represent whether this seat number is physically available on certain type of wagon or not(e.g. seat number 9 is physically available only in wagon type "2563-1").

I think I have found the value of N.M->max but I am not sure if it is so, because I have done this by visually rearranging the rows so I can decide if it is the best option. I have chose among 4 different options that I have considered.

The results are put in the second sheet. The best option I have chosen is M=13, N= 36 where M.N=468.

I need to describe this results with some mathematical method. So if you can help me with the tools that I should be using here and the tests to convey.

Thank you!

Greetings,
Rosko

I am attempting to run my data utilizing a Wilcoxon Rank Sum Test on MS Excel. I was wondering if anyone had any ideas of a good tutorial on how to do that?

I've searched YouTube but it was not helpful in regards to my specific set of data. Its really a simple analysis of Pre/post survey answers of 5 questions. The participants were anonymous for both Pre and Post so i'm running it as independent (unpaired).

Was wondering if anyone knew a good free or cheap program that runs a wilcoxon rank sum?

I would so greatly appreciate it.
