Quizplus · Accepted Answer

The number of kilometres a truck is driven is a quantitative variable, specifically a ratio variable, as it has a true zero point (i.e. if the truck has not been driven, the value is 0). Nominative variables are categorical variables with no inherent order or ranking (e.g. eye color), ordinal variables have categories with a natural order or ranking (e.g. education level), and interval variables have equal intervals between values but no true zero (e.g. temperature in Celsius). "Maintenance" is not a statistical term and is not a type of variable.
