After a long day working on the particle accelerator, you and your friends head to the arcade to unwind. The lights go out for a second, and when they come back, there before you gleams a foosball table. Always game, you insert your...

The word "normal" is often used as a synonym for "typical," "expected," or even "correct." By that logic, most people should fit the description of normal. But time and time again, so-called normal descriptions of our bodies, minds, and...

Today we’re going to talk about measures of central tendency - those are the numbers that tend to hang out in the middle of our data: the mean, the median, and mode. All of these numbers can be called “averages” and they’re the numbers...

In order to truly understand differences among animal lifespans, we need to stop thinking about a specific number and start thinking about a distribution.

Today we're going to talk about Chi-Square Tests - which allow us to measure differences in strictly categorical data like hair color, dog breed, or academic degree. We'll cover the three main Chi-Square tests: goodness of fit test, test...

We're going to finish up our discussion of p-values by taking a closer look at how they can get it wrong, and what we can do to minimize those errors. We'll discuss Type 1 (when we think we've detected an effect, but there actually isn't...

While politics is generally seen as the domain of a civics class (and Craig did a great job of teaching US Government & Politics elsewhere on this channel!) it’s something that sociology is interested in too. Today we’re looking at the...

In this video Paul Andersen explains how the macroscopic measure of temperature can be related to the average kinetic energy of molecules in motion. The Boltzmann constant and distribution can be used to calculate the root mean square...

Today we're going to begin our three-part unit on p-values. In this episode we'll talk about Null Hypothesis Significance Testing (or NHST) which is a framework for comparing two sets of information. In NHST we assume that there is no...

Today is the day we finally talk about the normal distribution! The normal distribution is incredibly important in statistics because distributions of means are normally distributed even if populations aren't. We'll get into why this is...

When collecting data to make observations about the world it usually just isn't possible to collect ALL THE DATA. So instead of asking every single person about student loan debt for instance we take a sample of the population, and then...

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...

In this video Paul Andersen explores population dynamics of the human population. The population has show exponential growth since the industrial revolution and all countries will eventually move through the demographic transition. If...

In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law...

Today we're going to introduce bayesian statistics and discuss how this new approach to statistics has revolutionized the field from artificial intelligence and clinical trials to how your computer filters spam! We'll also discuss the...

Test statistics allow us to quantify how close things are to our expectations or theories. Instead of going on our gut feelings, they allow us to add a little mathematical rigor when asking the question: “Is this random… or real?” Today,...

By analyzing raw data on violent incidents in the Iraq war and others, Sean Gourley and his team claim to have found a surprisingly strong mathematical relationship linking the fatality and frequency of attacks.

New ReviewWeight Distribution! WOW!

Industry Key Success Factors are the 5-6 core competenices that seperate the good from the great firms in an industry. You look at what customers want, how firms comptete in their industry, and if there are any issues...

Italy is ranked among the top nations in the world for its standard of living. Even so, a constant refrain that’s heard when people talk about Italy is how divided the country is between north and south. For centuries, northern Italy has...

In this video, explore the benefits of EtherChannel in increasing bandwidth and providing redundancy in a network.

In this video, gain an overview of WAN technologies and how they differ from LANs.

After learning how to use the one-way ANOVA, we will try to understand how to use the F-distribution to conclude the analysis results.

While performing the hypothesis testing and general statistics, you will learn more about the p-z combination and the normal distribution.
