• Quantitative and qualitative methods are complementary and can help
researchers avoid the limitations of a single approach.
• A mix of qualitative and quantitative research should be used in all research
studies.
• Using mixed methods is not as popular as a research strategy as it was a decade
ago.
• An advantage of mixed methods research is that people are more likely to
participate because the experience is enjoyable
