I am on my way to meet my tutor for research methods in Psyc. I took Stats last semester but for some reason levels of measurement never took root. I just watched your utterly fantastic video, made concise notes, and I now have a working understanding of LOM!! Thank you. ❤🌟Also, I always forgot their order until I realized the concept had the best acronym ever:NOIR
