This has to be one of my favourite videos at the moment as it deals with something which seems complicated but which, when you scratch the surface, isn't. Welcome to the video on the exact distribution of the sample proportion. Following on from the previous video, I take a look at how to find the mean and standard deviation of a sample proportion. We look at how, with large values of n, we can use the binomial approximation to find probabilities of sample proportions. We can also use combination theory too! A long but well-explained example (if I do say so myself) shows the power of the binomial distribution and sample proportions. So much fun had!
