What can I expect today? Intro to Social Network Analysis Case study examples Tool demonstrations Further resources
7
What is Social Network Analysis?
8
Social Network Analysis (SNA) Social network analysis is not just about Facebook.
9
Social Network Analysis (SNA) SNA is a way to look at relationship information and interactions.
10
Social Network Analysis Applying graph theory to sociological studies Nodes Links Flow
11
SNA Graph
12
SNA Graph and Matrix = ABCD A-110 B1-11 C11-0 D010-
13
Metrics Overview
14
What is does your graph represent? What are the nodes? What are the edges?
15
An Undirected Graph Task: Determine Degree
16
Deg(A) = 4 Deg (B) = 2
17
Directed Graph

Density
20
Density: First Ask How Many Possible Relationships?
21
Density = Actual Ties / Possible Ties
22
This graph has a Density of.4
23
Paths: Get from A to D Walk ACED Length 3 Walk ABD Length 2 Walk AD Length 1 This is our Shortest Path
24
Shortest Paths are needed so we can calculate closeness centrality
25
Closeness Centrality Node A vs. Node C
26
Graph Metrics VertexDegree In- Degree Out- Degree Betweenness Centrality Closeness Centrality A 0.111 B 0.167 C 0.200 D 0.125 E
27
Closeness Centrality of Node A ToBCDE From A ABABCABCDABCE Length1233
28
Closeness Centrality as Average Shortest Path Length 1.Identify Shortest Paths to all other nodes 2.Identify the length of those paths 3.Average those lengths
29
Closeness Centrality of Node A = 2.25 ToBCDE From A ABABCABCDABCE Length1233
30
Betweenness Centrality Potential Measure of Brokerage For a particular node, how many shortest paths is that node inside?
31
ABCDE A ABABCABCDABCE B BCBCDBCE C CDCE D DCE E
32
What is the Betweenness Centrality of Node B?
33
Focus on Node B ABCDE A ABABCABCDABCE B BCBCDBCE C CDCE D DCE E

35
Eigenvector Centrality Not just who you are connected to, but who are they connected to?
36
Eigenvector Centrality is a way to distinguish nodes with equal degree.
37
Compare Nodes Y and Z
38
Both Have Degree 4
39
Node Y is Connected to a More Connected Node
40
NodeXL will calculate it for you!
41
Practical Applications: Context Matters
42
Recognize the Impact of Missing Data
43
Social Media Context Directed Graphs Provide Additional Detail
44
Mapping Examples Let’s dig into some case studies
45
Case Study: Girls Inc. DC Question: Who should Girls Inc. DC interact with on Twitter?

49
Case Study: Fundraising Question: What insights can we gain from mapping online contributions?
50
Kenya Fundraising
51
Egypt Fundraising
52
Campaign Overlap
54
Case Study: Online Audience Analysis Question: How does our online audience connect to ACDI/VOCA?
55
Survey of External Audience
56
Methodology for SNA Component Pulled data from external survey questionnaire Created edge lists Used NodeXL to analyze connections Used SPSS (statistical analysis software) to create cross- tabulations
57
Findings Bipartite graph without isolates (i.e., without “No” responses)

Practical Steps: Using NodeXL
65
Include Attributes on the Vertices Page
70
NodeXL demo Which NTCs have you been to? D.C. Minneapolis San Francisco Atlanta
71
What do I do now? 1.Download NodeXL 2.Identify what data you want to map Online and offline Current audience, fundraising, etc. New audience opportunities 3.Be flexible. Be curious Ask questions Look for patterns Repeat investigations
72
Thoughts and questions? Experiences to share?
73
Remember networks are fluid. You can shape them with both online and offline interactions.
