ARAM picks, a statistical studying

Hello there, some of you maybe have wondered how often each champion appears in a serie of "several random" games. Currently i considered my 39 last games as I don't have much time to spend on lol... Of course I intend to increment it.

I'be begun to complete an excel file containing so far :

  • How many times each champion was played ( goes from 0 times to 7=> Ziggs for instance)
  • the apparition frequency distribution compared to a normal one using the same parameters (mean + sigma).

It's aim is to help me to ask several questions :

  • How does the frequency distribution look like at N > 100 with a mean >> 0 ? Can it be considered as "normal" => fair
  • How could the random selection system be improved (even chance for each champ), even if we can pass more or less through thanks our dices etc...

Eventually, I would like to know what you think about it + any ideas/remarks ? corrections in particular ? I would actually need help with the probability computations when you use a dice ^^ (I'm a dumb physicist).

Aram is busted

Your research sounds interesting, but please remember these couple of factors while you do it:

  • You do not know the champion pool structure of the other players.
  • Rerolls change the team compositions towards "better" ARAM team compositions.
  • Dodges change the team compositions towards "better" ARAM team compositions.
  • Please note: "better" above is subjective term and varies from person to person.

The first factor tells that you cannot use the champion data from other players to get any reliable data; they can have widely different champion pools and that will affect your research.

The last two factors tells that you have to use the initial champion you get for your research, if you wish to see if some champion comes from random more often than other. If you used the final result, your results will be skewed towards the better ARAM champions. You will need to consider changes to own champion pool and the free to play champions of the week in your research to get good results. And finally you will need thousands of games to get reliable results, so good luck with that.

I much rather play and have fun, than start doing work like research without pay, but people are different; I hear some people even love the work they do. I hope you have fun doing your research for as long as you happen to do that. :)
