With the nominal scale, there is no relationship between the values; there is no relationship between the categories blonde hair and black hair when looking at hair color, for example. This allows for a direct comparison between categories such that the difference between any two sequential data points is exactly the same as the difference between any other two sequential data points. Also, we can add, subtract, multiply and divide weights at the real scale for comparisons. Apart from the temperature scale, time is also a very common example of an interval scale as the values are already established, constant, and measurable. Shoes are assigned a number to represent the size, larger numbers mean bigger shoes so unlike the nominal scale that just reflects a category or class, the numbers of an ordinal scale show an ordered relationship between numbered items - we know that a shoe size of 8 is bigger than a shoe size of 4. These categories of shoes has no ordering (greater than, less than, equal to), are mutually exclusive and exhaustive. Quantitative data can be expressed in numerical values, making it countable and including statistical data analysis. In the ordinal level of measurement, the variables are still classified into categories, but these categories are ordered and there is no equivalent distance between the categories.
