I've looked through a lot of literature available online, including this forum without any luck and hoping someone can help a statistical issue I currently face:
I have 5 lists of of ranked data, each containing 10 items ranked from position 1 (best) to position 10 (worst). For sake of context, the 10 items in each lists are the same, but in different ranked orders as the technique used to decide their rank is different.
*Example data: List 1 List 2 List 3 ... etc
Item 1 Ranked 1 Ranked 2 Ranked 1
Item 2 Ranked 3 Ranked 1 Ranked 2
Item 3 Ranked 2 Ranked 3 Ranked 3
... etc*
I am looking for a way to interpret and analyse the above data so that I get a final result showing the overall rank of each item based on each test and its position, e.g.
Result
Rank 1 = Item 1
Rank 2 = Item 3
Rank 3 = Item 4
... etc
Does anyone know how I can interpret this data in a statistically sound method (at a post graduate / PhD applicable level) so that I can understand the overall ranks signalling the importance of each item in the list across the 5 tests please? Or, if there is another type of technique or statistical test I can look into I would appreciate any hints or guidance.
(It maybe also worth noting, I have also performed the simpler mathematical techniques such as sums, averaging, minimum - maximum tests etc, but do not feel these are statistically important enough at this level).
Any help or advice would be greatly appreciated, thank you for your time.
