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

Researchers can ensure the validity and reliability of their findings when combining qualitative and quantitative data by using triangulation, which involves comparing and contrasting data from different sources to confirm findings. They can also establish inter-rater reliability by having multiple researchers independently analyze the data and compare their results. Additionally, researchers should clearly document their research methods and decisions to enhance transparency and allow for replication of the study. Finally, researchers should consider the limitations of each data type and address potential biases through thoughtful data collection and analysis techniques.
