Randomness: Crash Course Statistics #17

There are a lot of events in life that we just can’t predict, but just because something is random doesn’t mean we don’t know or can’t learn anything about it. Today, we’re going to talk about how we can extract information from seemingly random events starting with the expected value or mean of a distribution and walking through the first four “moments” – the mean, variance, skewness, and kurtosis.

Note: There are many formulas to calculate skewness and kurtosis (https://www.itl.nist.gov/div898/handbook/eda/section3/eda35b.htm), our formulas deal with what they have in common, their moment generating functions.

Controlled Experiments: Crash Course Statistics #9

We may be living IN a simulation (according to Elon Musk and many others), but that doesn’t mean we don’t need to perform simulations ourselves. Today, we’re going to talk about good experimental design and how we can create controlled experiments to minimize bias when collecting data. We’ll also talk about single and double blind studies, randomized block design, and how placebos work.
