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. Here are some examples of Quantitative variables
