Underlying any research project, regardless of its intended purpose, are assumptions about what constitutes knowledge. These assumptions, known as epistemological assumptions, are foundational in the development of criteria for assessing the value or worth of data generated by research.

Adopting a scientific perspective inevitably leads to the subject matter of this chapter, thinking quantitatively.
This chapter explores how quantitatively oriented communication scholars think--and why they think as they do. Earlier chapters focused on establishing a theoretical base for communication study; this chapter and the next explore how scholars test their theories.
