Bootstrapping Main Ideas!!!

Bootstrapping is one of the simplest, yet most powerful methods in all of statistics. It provides us an easy way to get a sense of what might happen if we could repeat an experiment a bunch of times. It turns point estimates into distributions that can be used to calculate all kinds of stuff, including standard errors, confidence intervals and even p-values. In this video, we show how it can be used to calculate standard errors and confidence intervals. In Part 2, we'll see how to calculate p-values.

So 8^8 over counts the total number of useful combinations and the true number is 15 choose 8, which is 6435 #StatQuest #Bootstrap #Statistics
