Variables in Excel

The word variable is often used in the study of statistics, so it is important to understand its meaning. A variable is a characteristic that may assume more than one set of values to which a numerical measure can be assigned.

Height, age, amount of income, province or country of birth, grades obtained at school and type of housing are all examples of variables. Variables may be classified into various categories, some of which are outlined in this section.

Nominal variables

A nominal variable is one that is only for name sake. It does not give any additional information regarding the subject to which the variable has been assigned. For example: Jersey numbers of cricketers, passwords etc.

Scale Variables Scale variables show the ordering and the exact difference between each. For example: Marks of students in various subjects.
