Sociometry was closely associated with small group research and a focus on interpersonal choices within affiliation networks.

While some use the term sociometry to refer to all research using quantitative scales, the term sociography is sometimes used to refer to a method of presenting data about complex individual relationships and networks in graph form. In addition to its social scientific purposes, discussed below, sociometric assessment of interpersonal choices has also played a role in therapy by helping facilitate constructive change in individuals and groups through greater interpersonal awareness. For this reasons, in some circles the term sociometry refers to a form of therapy related to psychodrama.In modern usage, the term network analysis has largely supplanted the earlier term sociometry, though both involve analysis of social networks by statistical and graphical methods.

Today, network analysis usually refers to quantitative analysis of relationships among network nodes (actors or objects) based on mathematical graph theory. The main purposes of this quantitative approach are (1) description and comparison of networks based on various coefficients such as those regarding the centrality or non-centrality of nodes- and (2) visualization of the connectedness of nodes in graphical form. UCINET is perhaps the current leading software package for network analysis of this type.Network analysis may be applied to affiliation networks such as those connecting Facebook friends, flow networks such as commercial trading relationships, reference networks such as scholarly citation patterns, linkage networks such as webpage links, grids such as power grids, and many other network types.TABLE OF CONTENTSTable of ContentsOverview 4Key Concepts and Terms 4Sociometric tests 4Sociometric representation 5Network data diagrams 6Network graphs 7Network data matrix formats 7Network Analysis with UCINET 11Overview 11Data input 12Network visualization 15Statistical analysis 16Centrality measures 24Statistical analysis 27Assumptions 28Measurement inerrancy 28Correlated data 28Group size 29Model specification 29Ecological fallacy 29Frequently Asked Questions 29Where can I find out more about network analysis?
