How confident?

• gburt 13y ago
  sig=0.05, but please don't trust that for anything meaningful. This is sloppy 8am blog post response statistics. My personal confidence is basically 0. I just wanted to communicate the idea that 60 impressions was insufficient to make this judgement.

    If I'd do such a study, I'd pick a lower confidence interval, like 0.2. This is not a big scientific break through, or a business critical decision. This is a theorem that we're evaluating to be worthy of deeper investigation. If there's an 80% (also known as 'a significant') chance that the conversion rate is significantly lower than that of Google hits then I'd say that warrants deeper investigation. That's why it's important to always begin research with a hypothesis, not just randomly throw a confidence interval of a something in there :)
