How do you know if a variable is categorical or quantitative?
Quantitative variables are any variables where the data represent amounts (e.g. height, weight, or age). Categorical variables are any variables where the data represent groups. This includes rankings (e.g. finishing places in a race), classifications (e.g. brands of cereal), and binary outcomes (e.g. coin flips).
How is age classified as a categorical variable?
Age as a quantitative variable contains more information than as a categorical variable. If you were to represent age as a categorical variable, then you are doing away with the natural ordering of the ages you’d have by leaving it as a quantitative variable.
Is age a categorical or continuous variable?
A variable is said to be continuous if it can assume an infinite number of real values. Examples of a continuous variable are distance, age and temperature.
How do you tell the difference between categorical and numerical data?
Numerical Value Both numerical and categorical data can take numerical values. Categorical data can take values like identification number, postal code, phone number, etc. The only difference is that arithmetic operations cannot be performed on the values taken by categorical data.
How do you tell if categorical data is ordinal or not?
Ordinal data is a type of categorical data with an order. The variables in ordinal data are listed in an ordered manner. The ordinal variables are usually numbered, so as to indicate the order of the list. However, the numbers are not mathematically measured or determined but are merely assigned as labels for opinions.
How do you tell the difference between nominal and ordinal?
Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.
