Randomness - Crash Course Statistics
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...

Statistics & Mathematics for Data Science and Data Analytics - Statistical Moments
Here, we will understand the concepts of statistical moments, which generalizes what we already know about the central tendency measures and spread/dispersion.

Julia for Data Science (Video 17)
Julia is an easy, fast, open source language that if written well performs nearly as well as low-level languages such as C and FORTRAN. Its design is a dance between specialization and abstraction, providing high machine...

Kurtosis
Kurtosis is a measure of weather data is peaked or flat. It will be displayed as a curve with long tails and a high peek. Each of the various kurtosis curves of distribution are describes and explained.

Khan Academy: Statistics: Sampling Distribution of the Sample Mean
Video reviews the central limit theorem and uses a simulation to illustrate sampling distributions and how they approach a normal distribution with larger sample sizes even if the original distribution was not normal. Also discusses the...

Khan Academy: Statistics: Sampling Distribution of the Sample Mean 2
Video discusses the effect of sample size on the sampling distribution. Shows using a simulation how as sample size increases the sampling distribution becomes more normal and the standard deviation decreases. Also discusses the effect...
