This culls some of the main approaches to analyzing social networks. Then, it introduces the use of the freeware tool NodeXL, which is an add-in to later versions of Microsoft Excel. This tool enables the extraction of social network data from various sites' APIs (Twitter, Facebook, Flickr,YouTube, and others), the computation of graph metrics, and then a half-dozen node-link visualizations from the data. This tool was created under the auspices of the Social Media Research Foundation (SMRF) and distributed on Microsoft's CodePlex. http://www.merlot.org/merlot/viewMaterial.htm?id=80738 Este sitio Web es un curso de valoración estadística; es decir, para adquirir un sentido a la manera del razonamiento estadístico.
