๐จ๐ป๐ฑ๐ฒ๐ฟ๐๐๐ฎ๐ป๐ฑ๐ถ๐ป๐ด ๐ฆ๐ถ๐บ๐ฝ๐๐ผ๐ป'๐ ๐ฃ๐ฎ๐ฟ๐ฎ๐ฑ๐ผ๐ ๐ก Simpsonโs paradox is a statistical phenomenon where the relationship between two variables changes if the population is divided into subcategories. In the following animation, we can see how the linear relationship between two variables is inversed, if we take into account a third categorical variable. Simpson's paradox highlights the fact that analysts should be diligent to avoid mistakes.

Always love how simply that gif explains what would otherwise be a difficult concept to grasp in introductory statistics
Can anyone give an example, please?
Giannis Tolios , what's the usecase of Simpson's Paradox in a real world scenario ?
There's no paradox. This is just the fact that fixed effects should be taken into account in panel data.
Example for this is presented by higher mortality in vaccinated people between 10 and 59 years old in England in 2021. Explanation why this produce (false) argument for antivaxers is presented in: https://www.ntu.ac.uk/about-us/news/news-articles/2021/11/in-the-wrong-hands,-vaccination-statistics-can-prove-deadly-simpsons-paradox-shows-why
This is also called a โsuppression effectโ in regression and causal modeling . Here is an article on this topic in the field of epidemiology: https://pubmed.ncbi.nlm.nih.gov/32190094/
Wow! May you send me this video?
Great visualization Giannis!
Attendees of my recent Loss Reserving with R workshop will recognize this visual and Simpson's paradox. Actuaries in reserving: were you aware that most of the data you work with has this property?

1yEvery time I see someone talking about Simpson's paradox I need to post the Simpson's Simpson's paradox
