Working with data requires good data science skills and a deep understanding of different types of data and how to work with them. In summary, nominal variables are used to name, or label a series of values. In ordinal scales, values given to measurements can be ordered. Ordinal data is considered as "in-between" qualitative and quantitative data. Performance & security by Cloudflare.
