Guns in the Home and Risk of a Violent Death in the Home: Findings from a National Study
I am hoping you'll look at this and help me explain why it is (Or isn't) flawed.
It seems to me that excluding know factors from a survey, or over-sampling a specific group, would skew the results towards what you are looking for.
I have a friend who has cited this study, but after reading it, it seems like they set out an agenda and used only the data that supported their presumptions.
Thanks in advance. I know we have Doctors, Lawyer, statisticians and many of very knowledgeable people here who could explain this better to me and my friend. Thanks.
