It was actually your comments which inspired me to try and come up with an improved system.
If the code is well written, it should be as simple as entering the five numbers corresponding to the number of votes (the programme would show "How many Sub Zero votes were there?" and you'd type the number and hit enter) and then the programme would give you a few outputs, including the original score, standard deviation, adjusted score, and total votes. Even then, though, the rawness of it can be intimidating.
To be honest I'll probably do it in LabVIEW once I've got the basic ideas sorted since LabVIEW is much better at processing data and it's also much more user-friendly. Unfortunately it's much less common since it's not free, so if I do it that way I'll upload the VI but I doubt anyone else will be able to use it. I'd also consider doing it in MATLAB but that's not free either.
Anyway, I'll keep you all posted on how it goes.
@GranTurismo916 Do you have all the raw data from the cars already in an Excel spreadsheet or similar format? If so, I may ask to use it at some point. If not, well, a raw data sheet might be useful... I'm going to spend way too much time on this.
