• Nominal – Assigning items to categories e.g. blue eyes. Frequency distributions are usually used to tabulate and analyze problems involving nominal data. Nominal data is qualitative (or categorical) • Ordinal – A set of data is said to be ordinal if the values belonging to it can be ranked. • Interval ‐ An interval scale is a scale of measurement where the distance between any two adjacent units of measurement (or ‘intervals’) is the same but the zero point is arbitrary. • Ratio ‐ Ratio data are continuous data where both differences and ratios are interpretable and have a natural zero.
