Quantitative Research Methods for Communication: A Hands-On Approach

Quantitative Research Methods for Communication: A Hands-On Approach is a relevant and accessible guide to quantitative research. In clear, straightforward language, the authors encourage students to take an active, hands-on role in the learning process, giving them the tools they need to locate, conduct, collect and present their research. The authors use real communication studies and data sets to make communication research come alive for students. Students are not only introduced to new skills but also given the opportunity to immediately apply these skills in research scenarios. The text integrates helpful features throughout, including chapter objectives, case studies, data sheets, and key terms.
