  For today's applied statisticians and data scientists, collaboration is a
reality. Statisticians (and data scientists) may collaborate with domain
experts across academic fields, industry sectors, and governmental and
non-governmental organizations. Thus, statisticians must develop skills and
techniques for collaboration. To this end, we advance a framework called the
Qualitative-Quantitative-Qualitative (QQQ, pronounced "Q-Q-Q") approach to
systematize the content of statistical collaborations. The QQQ approach
explicitly emphasizes the importance of the qualitative context of a project,
as well as the qualitative interpretation of quantitative findings. We explain
the QQQ approach and each of its components as applied to statistics and data
science consultations and collaborations. We provide guidance for implementing
each stage of the approach and present data evaluating the effectiveness of
teaching the QQQ approach to beginning collaborators.
