CENTRALITY AND PRESTIGE
Measures of centrality and prestige
One of the most important uses of network analysis is
identication of most central units in a network.
Measures of centrality and prestige can be dened in two
different ways:
0 for each unit

As shown above, math is often used within the profession of a medical _
technologist. The major math concepts required include probability, StatiStics, and basic
algebra such as conversion. Using math, the job of a medical technologist may b'e
