Detailed explanation-1: -Nominal and ordinal are two of the four levels of measurement. Nominal level data can only be classified, while ordinal level data can be classified and ordered.
Detailed explanation-2: -Examples of ordinal variables include: socio economic status (“low income”, ”middle income”, ”high income”), education level (“high school”, ”BS”, ”MS”, ”PhD”), income level (“less than 50K”, “50K-100K”, “over 100K”), satisfaction rating (“extremely dislike”, “dislike”, “neutral”, “like”, “extremely like”).
Detailed explanation-3: -Ordinal data is a kind of qualitative data that groups variables into ordered categories. The categories have a natural order or rank based on some hierarchal scale, like from high to low. But there is no clearly defined interval between the categories.
Detailed explanation-4: -Unlike other data types, nominal data cannot be ordered or measured; it does not have equal spacing between values or a true zero value.
