I want to create a confidence interval for my KDR in Combat Arms.
If I gather information about my Kills and Deaths per match, I can get a mean and StdDev for kills or deaths per game, but how can I transform that information into a ratio of kills per death, given only x-bar kills and deaths and S kills and deaths?
I can just divide the means, but what do I do for the StdDevs?
