HOMEWORK ASSIGNMENT:
All students are obliged to hand in an assignment, which will be graded. The grade from this mini-course will form part of the final grade from the module "Behavioral Strategies for Business." The homework should be handed in to me via email.
The assignment has to be done individually by each student.
Deadline: April 24, 2024.
For the task, find data on a real-life social network. It can be any network of your choice. You can for example find a lot of network data on the Stanford Large Network Dataset Collection or Network Repository, but many other sources of data exist online. Just be creative! Your task is the following:
(a) Read the network into R
(b) Describe what the network represents and visualize it clearly. If the network is too large, visualize one part.
(c) Analyze the network and describe briefly the properties of the network.
