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 lets us do just that! SciShow is supported by Brilli

Guinness, Student, and the History of t Tests (10-1)
We concluded our lesson on z tests with the sad realization that z tests rarely get used in the real world. Instead of using a z test we compare samples to populations using a t test. William Sealy Gosset, a master brewer and a scientist at the Guinness brewery in Dublin, Ireland solved th

Why We Might Not Have Statistics Without Guinness Brewery – A History of the t-Test (10-0)
William Sealy Gosset, a master brewer and a scientist at the Guinness brewery in Dublin, Ireland solved the problem of using small sample sizes by adjusting the variance estimates. He created Student’s t Table and is the namesake of Student’s t Test. We answer whether Guinness Brewery knew

The Assumption of NORMALITY in Parametric Hypothesis Tests (16-6)
Parametric statistical tests require normality, which does not mean what many people think it means. I explain the true meaning of the assumption of normality, using Stats Blocks, and how to test this assumption with graphs or tests, such as Kolmogorov-Smirnov Test. The Central Limit Theor

Confidence Intervals using a t Distribution when Estimating Population (Week 13C)
Unfortunately, we rarely know the mean and SD of the population we are sampling. Yes, we can estimate population parameters from our sample statistics, but the SD estimations are biased when our sample sizes are small. Therefore, we need to adjust for that bias using a t distribution and a

The t Distribution: A BREWER’S Solution for Small Samples (13-4)
In the early days of statistics, the lack of replicability created skepticism that statistics could be a science. When using small samples, the results were inconsistent. William Sealy Gosset, a scientist-brewer at Guinness Brewing Company solved the problem of small sample sizes by adjust

How to Do a One-Tailed Hypothesis Test in JASP (10-9)
In statistics, we typically use a two-tailed (non-directional) alternative hypothesis. This video illustrated how and when to conduct a test with a one-tailed (directional) alternative hypothesis. This example uses a one-sample t-test, but this same technique will work for every other dire
