This innovative book explores how Q methodology offers a unique way to examine subjectivity, meaning people's viewpoints, in that it both differentiates and describes viewpoints, blending qualitative and quantitative research. The book provides accurate terminology and consistent practices, with examples of using Q to study subjectivity in a variety of contexts and disciplines. The book also frames Q within its mixed status - blending qualitative and quantitative research aspects from data collection to analysis and interpretation. The author aims to help readers to understand the basics of Q methodology as well as some "rules of thumb" in an easy to read yet accurate text in terms of processes and theoretical frameworks of Q. This is an essential text for those interested in using Q methodology in qualitative research and mixed methods research across a range of disciplines.
