Module 4 Quiz

Q.1. We have seen that in network science, it is assumed that networks are being produced by one of the following four different ways: random networks; scale-free networks; small world networks; hub&spoke / star network.

  • False
  • True

Q.2. Why do we study random networks?

  • No specific reason, this choice is just random
  • Because most social networks follow a random network structure
  • Because it helps us decide if a network is special
  • Because it is an abstraction of empirical research in social science
  • Because it provides a most simplistic model

Q.3. When simulating certain kinds of networks to derive certain network properties (such as the average degree, or the number of triangles), one can use numerical and analytical approaches. What is the difference?

  • For numerical solutions, you use traditional probabilistic calculus, for analytical solutions you use modern machine learning
  • For analytical solutions, you enumerate the options and basically count, for numerical solutions you use math to derive the results
  • For numerical solutions, you enumerate the options and basically count, for analytical solutions you use math to derive the results
  • For analytical solutions, you use induction, for numerical solutions you use deduction

Q.4. When studying phenomena like the spread of diseases, the diffusion of innovations, or the virality of opinions, the so-called giant component plays an important role. What have we seen regarding how giant components grow from random networks?

  • Small world networks are found at the sweet spot between giant components and network hubs
  • The majority of nodes are connected to the giant component rather suddenly after passing a certain tipping point or threshold
  • Giant components only emerge in scale-free networks, where there are exponentially few nodes many links
  • A giant component will only emerge after every node in the network has sufficient Eigenvector triality

Q.5. In network analysis, what does “preferential attachment” mean?

  • The Erdos-Renyi random graph exhibits a threshold function with a giant component
  • Fat tails are scale-free fractals, with exponentially few nodes with exponentially many connection
  • The probability of a node to connect with new nodes, corresponds to the number of existing degrees of a node

Q,6. What does it mean that something is distributed according to a power-law?

  • Exponentially few, have exponentially much, and exponentially many, have exponentially little
  • 68% of the cases lie within one standard deviation and 95% within two standard deviations
  • 80 percent of outcomes (outputs) come from 20 percent of causes (inputs), aka the 80-20 rule
  • A list of hubs of scale-free popular kids on the block becomes a straight line when taking a logarithm

Q.7. We got to know a selection of stylized mechanisms that grow network structures that are typically found in social networks. Which of the following is true about them?

  • Erdos-Renyi networks have a high level of clustering and small average path length
  • Scale-free networks can be grown by a logic of preferential attachment
  • Degree distributions in small world networks follow a power law distribution
  • Small world networks are also known as Erdos-Renyi networks

Q.8.When social scientists say that societies consists of small world networks, what do they mean?

  • Exponentially few, have exponentially much, and exponentially many, have exponentially little
  • People have both close connections in tight groups and quick access to everybody
  • People unexpectedly often meet people with whom they have common acquaintances (“what a small world?!”)
  • People can reach all other people in the network quickly (small closeness centrality)

Module 5 Quiz

Q.1 Airline routes often evolve toward so-called hub-and-spoke or start-network configurations. Why is that?

  • Because they have low costs in maintaining links, but high benefits
  • Due to the their robustness, even if nodes fail
  • Because they have small average path length
  • Star networks have high clustering coefficients, allowing for groups to compete

Q.2 If there is almost no cost to create and maintain connections, but large benefits, what network will evolve?

  • A clique
  • Star network
  • Scale free network
  • Small world network

Q.3 In lecture, we grew efficient networks by adding links, until they were stable (following Jackson’s symmetric connection model). We assumed commonly used variables that eventually shaped and guided the evolution of the network. Which was NOT one of them?

  • Indirect benefits from connections not directly linked to the node
  • Benefits from maintaining direct connections
  • Cost of maintaining direct connections
  • Cost of maintaining indirect connections not directly linked to the node

Q,4 In the lecture, when talking about dynamic networks, how did we define “social efficiency”?

  • Redistribution mechanisms were used to introduce social fairness among people
  • No node in the network can improve its situation
  • It has the largest sum of the net benefits (benefit-costs) for the whole society
  • The social benefit is fairly distributed among everybody
  • The social network is stable and does not change during the time of observation

Q.5 In order to have a stable network configuration, a network must reach _______. This is when _______ changes in the network. Fill in the blanks with:

  • Evenness; everything
  • Symmetry; nothing
  • Equilibrium; everything
  • Equilibrium; nothing

Q.6 When talking about dynamic networks in lecture, how did we define “social stability”?

  • Redistribution mechanisms were used to introduce social fairness among people
  • No node in the network can improve its situation
  • The social network does not change during the time of observation
  • It has the largest sum of the net benefits (benefit-costs) for the whole society
  • The social network does not change for half of its lifetime

Q.7 In the lecture, after we grew a uniquely efficient network we found that it was unstable. What did we do to stabilize the efficient structure of our network?

  • We redistributed resources, balancing costs, and benefits
  • We added extra nodes, alleviating the burden on individual nodes
  • We reconfigured the network to a small world network structure
  • We added extra links that created more stable paths
  • We used taxing/bargaining to assure that most nodes were well off

Q.8 If a disease is spreading in a scale-free network, and you want to stop it with vaccination efficiently, what would you do?

  • Vaccinate the nodes with high clustering coefficient
  • Vaccinate the nodes with six degrees of separation
  • Vaccinate randomly, following Erdos-Renyi
  • Stabilize the network with cross-subsidies
  • Vaccinate the hubs of the network

Q.9. Why do you need less steps to diffuse something in a scale-free network, compared with a random network?

  • Central hubs can reach many nodes very quickly
  • Scale-free small world Erdos-Renyi graphs follow preferential attachment
  • Exponentially many nodes are hubs and catapult the messages to many others

More About This Course

This course is intended to make a science’ of something at the heart of society: social networks.

Humans are natural network scientists because we constantly, almost unconsciously, compute new network configurations when thinking about friends and family (which are specific types of social networks), colleagues and organizational relations (other, overlapping network structures), and how to navigate delicate or opportunistic network configurations to save guard or advance in our social standing (with society being one big social network itself).

While such network structures have always existed, computational social science has assisted in revealing and studying them more thoroughly. T

he first section of the course focuses on network structure. This appears as static snapshots of networks, which can be complex and reveal important aspects of social systems. You will also visualize and analyze a network with software in our hands-on lab, which will help you appreciate the complexity that social networks can take on.

The second part of the course will examine how networks evolve over time. We want to know how we can predict what kind of network will form and whether or not we can influence network dynamics.


  • Define networks and learn about the languages they use.
  • Analyze a social network by manipulating data and visualizing a network.
  • Discuss the mechanisms that cause networks to form.
  • Using case studies, investigate social network analysis.
