Smart's "The differences in how CNN MSNBC & FOX cover the news"

https://pudding.cool/2018/01/chyrons/

This example doesn't demonstrate a specific statistical test. Instead, it demonstrate how data can be used to answer a hotly contested question: Are certain media outlets biased?

How can we answer this? Charlie Smart, working for The Pudding, addressed this question via content analysis. Here is how he did it:



And here are some of their findings:

Yes, Fox News was talking about the Clintons a lot.
While over at MSNBC, they discussed the investigation into Russia and the 2016 elections ore frequently.



While kneeling during the anthem was featured on all networks, it was featured most frequently on Fox
And context matters. What words are associated with "dossier"?



How do the different networks contextualize President Trump's tweets?

Another reason I like this example: It points out the trends for the three big networks. So, we aren't a bunch of Marxist professors ragging on FOX, and we aren't a bunch of Fake Newsers ragging on MSNBC: We can dispassionately look at the trends present across the spectrum. I think this is important in diverse classrooms with diverse opinions.

I think this example also shows some really good visualizations for different sorts of data, allowing users to easily comprehend trend across time, comparisons among the three networks, etc.

Moderation, esophageal cancer, and really hot tea.

You know what, I've been doing this blog for YEARS and I don't have a single example of moderation. Until now.

This CNN story summarizes brand new research findings that indicate that alcohol and/or tobacco use mediate the relationship between drinking really hot tea and developing esophageal cancer.



So, the really hot tea-cancer relationship does not exist in the absence of smoking and/or alcohol consumption, but it is there if you do indulge in either smoking or alcohol consumption.

And writing this post reminded me of this Arrested Development moment:



Aside:
-This article could also be a good example of the need for cross cultural research: Americans don't love tea as much as other parts of the world do. And, super hot tea (145 degrees +) is very popular outside of the US and Europe. The present research was conducted in China.
