The Brewer Who Secretly Revolutionized Statistics | Great Minds: William Gosset
When you have a study with a small sample size, how do you know that the results represent the broader population? Well, thanks to a brewer who needed to assess beer quality in the early 1900s, we now have a simple statistical test that...

TED-Ed: What is "normal" and what is "different"? | Yana Buhrer Tavanier
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...

Mean, Median, and Mode Measures of Central Tendency - Crash Course Statistics
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...

Standard Deviation
In this video Paul Andersen explains the importance of standard deviation. He starts with a discussion of normal distribution and how the standard deviation measures the average distance from the mean, or the "spread" of data. He then...

The Normal Distribution - Crash Course Statistics
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...

The Shape of Data Distributions - Crash Course Statistics
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...
