    Q: How many data points are needed to tell (to some level of confidence) if they are drawn from a normal distribution or not? Is there a good procedure to answer this question?

    Really useful talk-- any chance you can share the link to the notebook here?

    Excellent and thought provoking talk. 10:42 Is standard deviation really the same as standard error?

      Thanks! Yeah, that was a tiny slip up on my part. They are both measures of variability. SD reflects variability in a sample. SE reflects variability across multiple samples from the population. In the context of my notebook, I'm calling np.std() on a sampling distribution of means, hence my tiny slip up 🙂🙃!

      Yes, the standard error is the standard deviation *of the distribution of sample means*.
