ceo ' s arent cashiers mang <| sep |> Hey man , just want to clarify how stats work and I ' m sure you understand this given how well you did your analysis here . I ' m not really sure we can say cold hard stats without misleading readers who don ' t fully understand what ' s going on . By the nature of statistics you can ' t for sure prove or disprove anything , you can just be confident , but not 100 % certain that you ' ve found the right answer . I just feel like cold hard statistics though I understand what you mean with that wording would be misleading to people who don ' t know that you can ' t ever conclude anything 100 % using any real statistical method . After that first sentence or so , love the post , great work as always .
