Quantitative Variable Examples
There are two types of data: qualitative
and quantitative. Quantitative data differs in amount, or quantity;
qualitative data differs in type or quality.
Examples of quantitative data are those
that can be measured with an ordinal or ratio scale.
An ordinal scale does not have a true
zero, so multiplicative relationships can't be expressed with the
quantitative variables obtained from it. For example, a Fahrenheit
scale has a value of zero, but it does not indicate a zero amount
of what it measures, i.e., tempeture. As such it does not make sense
to say that 50 degrees is twice as hot as 25 degrees.
The ratio scale does have a true zero,
so multiplicative relationships can be captured with it. Age, for
example, is a ratio scale and it makes sense to say that a 1000 year
old antique is ten times older than a 100 year old one.
