    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

    Thanks so much Emma. Quick Q? If I am using a Likert scale which sounds ordinal but has a numerical number attached to each rank, example Strongly Disagree = 1 and Strongly Agree = 6, would this still be ordinal data or is it now numerical data?

    It is going to be ordinal; the reason is; your Likert-scale values are categorical data depending on the type of scale for example (1. very poor 2. poor 3. acceptable 4. good 5. very good) or (1. very likely 2. unlikely 3. Neutral 4. likely 5. very likely). Given the example you sighted, there is a meaningful order in the categories and it is ranked with 1 being strongly disagreed, and 6 strongly agree. Also, because you're assigning numbers to them (1,2,3,4,5) does not make it numerical. The number assigning is to allow easy analysis of the data because likert scale is mostly qualitative. Hope this helps..
