In this video, we’ll uncover the true definition of a confidence interval, clear up some common misconceptions, and explain the difference between the incorrect and correct interpretations. In fact, published studies have shown that professional scientists frequently misinterpret confidence intervals.

 

 

In statistics, “types of data” are generally referred to as “levels of measurement”. We’re going to explore the four levels of measurement —Nominal, Ordinal, Interval, and Ratio. Each level gives us important information about the variable and supports different types of statistical analysis.

 

 

This video is about analysis of variance, or ANOVA for short. We discuss what an ANOVA is and why you need it. We look at the hypotheses and the prerequisites for an analysis of variance, and I show you how to calculate an ANOVA and what the equations behind an ANOVA are. Finally, we discuss how to interpret the results and take a look at the post-hoc test. First of all, there are different types of analysis of variance. The simplest and most common form is the one-way analysis of variance. And this video is all about the one-way analysis of variance.

 

 

Are you relying on the t-test in every situation? It might be time to rethink that approach! In this video, we dive into three specific cases where the t-test can lead you astray, and explain why alternative methods are better suited for these scenarios. Whether you’re in research, data analysis, or just curious about statistical techniques, understanding when not to use the t-test is crucial.

 

 

In this video, we delve into the fundamentals of Control Charts, a vital tool in quality control and process management. Learn how to monitor processes, detect variations, and maintain consistent quality over time.

 

 

The p-Value has been a critical tool for researchers across various fields, helping them determine the significance of their results. However, it has also been the subject of intense debate and scrutiny. In this video, we break down the pros and cons of using the p-Value in scientific research.
