Table 6.6 Mixed-Methods Designs, Purpose, and Notes
Title Purpose Notes
Convergent parallel Analyzes data independently
and then merges data for
interpretation
Design in which the quantitative
and qualitative data are collected
concurrently and both types of
data are prioritized equally
Explanatory sequential Used when quantitative
findings are explained
and interpreted with the
assistance of qualitative data
Sequential design with
quantitative data collected in
the initial phase, followed by
qualitative data
Exploratory sequential
designs
Used when qualitative
results need to be tested
or generalized or for theory
development or instrument
development
Sequential design with qualitative
data collected in the initial phase,
followed by quantitative data
Multiphasic Useful in comprehensive
program evaluations
by addressing a set of
incremental research
questions focused on a
central objective
Combines the concurrent and/
or sequential collection of
quantitative and qualitative data
sets over multiple phases of a
study
Though quantitative and qualitative studies both use systematic processes, they
have distinct differences in their worldviews:
■■ Quantitative studies are objective; they test theory (deductive), involve
the use of numbers, and produce findings that are meant to be generaliz-
able.
■■ Qualitative studies are subjective; they generate knowledge through the
process of induction, involve the use of words, and produce findings that
are not meant to be generalizable.
