I’m currently on my data analysis stage in my dissertation which involves collecting social media posts in an online community from 30plus participants. I will conduct a thematic analysis using a codebook on these posts. One of the questions of my panel is that how can I ensure trustworthiness in my coding scheme. I plan to have another researcher who will also check on how I apply a code. And we will discuss our differences. What would be a good way to answer the question of the panel? Should I code first, and then he checks on my code and discuss our disagreement? I am thinking of checking code application between me and the other researcher for every case instead of doing it in one go. Thank you in advance.
