How can researchers ensure the reliability and validity of their findings when combining qualitative and quantitative data in their study analysis?

Validity
Researchers can ensure the reliability and validity of their findings when combining qualitative and quantitative data by using a mixed methods approach that involves triangulation, where multiple sources of data are used to corroborate findings. They can also establish clear criteria for data collection, analysis, and interpretation to maintain consistency and accuracy. Additionally, researchers should consider the limitations and biases of each data type and address them through careful data integration and interpretation. Regularly engaging in reflexivity and seeking input from peers or experts can also help enhance the credibility and trustworthiness of the study findings.
