## Faculty and Graduate Student Presentations

## Mathematics & Statistics Seminar

Friday, December 1st - 3:30pm -4:30pm in HSH 143

**SPEAKER: BEN GODON****THE CHROMATIC POLYNOMIALS OF**

GRAPHS

ABSTRACT: An introduction to graph coloring and

chromatic polynomials, and their construction on

simple graphs.

**SPEAKER: WILL SUTHERLAND****AN INTRODUCTION TO UNEQUAL****PROBABILITY SAMPLING AND****PROBABILITY PROPORTIONAL TO SIZE****SAMPLING**

ABSTRACT: As an undergraduate mathematics

student, when you are introduced to Sampling

Theory it’s with the requirement that each unit

has an equal probability of being selected in the

sample. What if that is not always the best

approach? This presentation will introduce the

concept of Unequal Probability Sampling as well as

a class of methods to implement such sampling

designs, Probability Proportional to Size Sampling.
