## Statistics 101: ANOVA, A Visual Introduction

Statistics 101: ANOVA, A Visual Introduction ANOVA allows us to move beyond comparing just two populations. With ANOVA we can compare multiple populations and even subgroups of those populations. In this video we will not be doing any calculations, looking at any formulas, or testing any hypotheses. This video offers a solid, conceptual foundation about […]

## Statistics 101: Understanding Correlation

Statistics 101: Understanding Correlation In this video we discuss the basic concepts of another bivariate relationship; correlation. Previous videos examined covariance and in this lesson we tie the two concepts together. Correlation comes with certain caveats and we talk about those as well. Finally we walk through a simple example involving correlation and its interpretation. […]

## Statistics 101: Type I and Type II Errors – Part 1

Statistics 101: Type I and Type II Errors – Part 1. If this video we begin to talk about what happens when our data analysis leads us to make a conclusion about a hypothesis which turns out to not align with the actual state of the world. These are called Type I and Type II […]

## Learning to Love Bayesian Statistics

Allen Downey Olin College of Engineering Presented at Strata NYC 2015 http://conferences.oreilly.com/strata/big-data-conference-ny-2015 Abstract: Bayesian methods are well-suited for business applications because they provide concrete guidance for decision-making under uncertainty. But many data science teams lack the background to take advantage of these methods. In this presentation I will explain the advantages and suggest ways for […]

## Statistics 101: Introduction to the Poisson Distribution

Statistics 101: Introduction to the Poisson Distribution In this video we discuss the basic characteristics of the Poisson Distribution using a real-world example involving a checkout line at a supermarket. Having a basic understanding of the binomial distribution is helpful, but not necessary. I also show you how to calculate Poisson probabilities on at TI […]

## What is Variance in Statistics?

## Statistics 101: Simple Linear Regression (Part 2), Algebra, Equations, and Patterns

So this video the next in our series about Simple Linear Regression. In our last video, we talked about the very basics of regression. First we discussed what residuals are. Then we learned about the sum of squares of the residuals. Lastly, we talked about how a regression model is actually a comparison to a […]
