Understanding Basic Network Analysis Concepts

Everyone talks about networking.  Social networks are increasingly important—from using Facebook to keep in touch with friends and family, to using professional contacts to find jobs.


Network of Actors and Actresses

Social network analysis is the study of the relationships between all the individual actors contained in one group.  With social network analysis, we can examine the workings of a group of interconnected people.  This is great for the social sciences because it allows the investigation of relationships at a small-world level.  Social network analysis shows the patterns and flow of the relationship dynamics within the group.

Ad Buys: FCC Data and (Partial) Transparency

Data about political advertising historically have been difficult to access, though recently the Federal Communication Commission (FCC) began implementing new disclosure requirements for TV stations.


FCC data allow for the examination of campaign spending in the Iowa Senate race. More about these graphs below.

Dazzling New Resource for the Discussion of Data


One of the monikers that history allots the early 21st century may be “The Age of Data”—not big data or little data—not quantitative data or qualitative data, but data of all sizes and shapes. The vast proliferation of information, particularly that which is now digitally available, provides scholars, students, and the general public both exciting new opportunities for exploration and significant challenges.

Today Grinnell’s Data Analysis and Social Inquiry Lab (known as DASIL, which we pronounce DAZZLE) is inaugurating a resource to assist faculty, students, and anyone else fascinated with data in their exploration of the world. A blog will initiate discussions of ways to find data, appropriate methods for evaluating data quality, and ideas about the analysis and visualization of both quantitative and qualitative data. Resources pages will provide, primarily interactive, visualizations of a wide range of data and data types. Eventually these will be augmented with data sets and class exercises that faculty at Grinnell have prepared and invite others to use and modify as desired.
