I am undertaking my first research study and getting to grips with NVIVO 12. I have completed initial coding for three interviews so far and have realised that I haven't kept note of how many new nodes I have added for each interview, which is something I would like to investigate. Is there an easy way of doing this? Or do I need to go back over my second and third interviews and complete the task manually? Would much appreciate guidance from any NVIVO 12 experts. Using a Mac version.
