Detailed explanation-1: -An Example: Age Age is, technically, continuous and ratio. A person’s age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough. It is meaningful to say that someone (or something) is 7.28 year old.
Detailed explanation-2: -i) The day of the week (i.e. Monday, Tuesday): NOMINAL because it just categorizes the variable.
Detailed explanation-3: -The short answer: Age is considered a ratio variable because it has a “true zero” value.
Detailed explanation-4: -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”).
