How can researchers ensure the reliability and validity of their study results when using a mixed methods approach to combine qualitative and quantitative data?

Researchers can ensure the reliability and validity of their study results when using a mixed methods approach by clearly defining their research questions and objectives, ensuring that the qualitative and quantitative data collected are complementary and provide a comprehensive understanding of the phenomenon being studied. They should also use appropriate data collection methods and analysis techniques for each type of data, and triangulate the findings to confirm consistency and convergence. Additionally, researchers should consider potential biases and limitations in their study design and interpretation of results to enhance the credibility and trustworthiness of their findings.
