Hi ! I'm doing an internship on software testing and I have to classify reported bugs. The bug list is important so I decided to make a sampling. I know that by doing a sampling I may introduce an error when I will generalize my result to the whole population, and I am ready to assume it. But I want to be able to measure the trust I can have in my work. I feel I have to use the "chi square" test. Is it true and are there other tests ?
The detail of my classification will depend on the amount of work I have to make as my time is limited (no big news in this !). In my case, I have ten categories with a sub-division in 33 categories (not for each category but for all of them). The number of reported bugs should be around 3000. (I could get a more precise number on this, but haven't searched yet). What should be the correct size of my sample if I use the ten categories? And if I use the 32 subcategories? I have some knowledge of statistics so I guess I could apply, and hopefully understand, any formula as long as I could find one. Thanks for your help, Louis Tillier.
