This dataset is formulated exclusively to capture the interactions between players. A simple game theory model of Prisoner’s Dilemma is the best example of a social network dataset in a two - person world. A social network dataset can get more complex because the real world has more than two people and they interact in more than one way. The interactions between people are not apparent in the traditional dataset. Whereas they are the main point of focus in a social network dataset. If we were to think of it as a conversation, social network data is a two - way conversation as opposed to the traditional data being a monologue. When we start analyzing this data, we start the process of social network analysis. In the above figure, the colored circles are the airports represented as nodes. The lines connecting them are the edges telling us the number of flights between them. 2 of 9

What is a matrix and how does a typical matrix differ from an adjacency matrix? Provide an example of both a typical matrix and an adjacency matrix (from the 3 you listed in #1). Answer 3: A matrix is an array of numbers – a rectangular arrangement of numbers into rows and columns. They are just tables. A matrix is nothing more than a rectangular arrangement of a set of elements. Rectangles have sizes that are described by the number of rows of elements and columns of elements that they contain. It is a methodical way to represent data that makes it easy to understand. A typical matrix / dataset will have subjects in the rows. Their subject’s attributes will be mentioned in the columns. Rows: The cases or subject of the study. Columns: The measured attributes for that subject (qualitative or quantitative). Using the same example as in Question 1 for traditional matrix. The table given below is a traditional matrix. It represents characteristics of individual airport in every row with no two rows related to each other.

Each node is represented by the circle which is our
