Theory triangulation is the use of more than one theoretical framework or perspective to explain and understand the data from the same phenomenon. For example, you can apply different models, concepts, or assumptions from various disciplines, such as psychology, sociology, or economics, to your market research data and to examine how they relate to your research questions, objectives, or hypotheses. This method can help you to broaden, deepen, or refine your data interpretation and to generate new ideas, hypotheses, or solutions for your market research problems. To ensure success with triangulating data from multiple sources for improved quality and credibility of your market research, careful planning and execution is essential. You should choose appropriate methods, sources, analysts, and theories that are relevant, feasible, and compatible with your research purpose and design. Additionally, it is important to collect and analyze data from multiple sources systematically, consistently, and ethically. Comparisons should be made critically, creatively, and collaboratively before communicating the findings in a clear, accurate, and convincing manner.
