On January 4, 2015, I will be shutting down the server that hosts The TV IV website. It has been a very long time since I've been able to put any decent amount of time into the site, and ad revenue is plummeting. I think it is time to shut it down or hand it off to someone who can keep it going properly. If you are interested in taking over the site's code and data, contact administrators at --CygnusTMtalk

Mean World Index

From The TV IV
Jump to: navigation, search

The Mean World Index is a mathematical analysis of how violent images in the media affect people. The study correlates the content of the programs with the social distribution of viewers, calculating percentages and a numerical index based on the responses of each group. The characteristics taken into account include those portrayed on screen and those traits spread across the audience. These characteristics include race, gender, and economic status (Signorielli 91-100).
