The range is the difference between the highest and lowest value of a set of data. In a certain way, we may consider as the same concept as the domain of a continuous function.
The Human Development Index (HDI) measures the developedment ofa country regarding several parameters. The following table shows the ranking of HDI of the countries of the European Union:
|The United Kingdom||$$16$$|
The country with the highest position in the ranking is Ireland (the fifth one), while the lowest is Romania in the position $$60$$.
And so, the range of this scoring is:
$$60-5 = 55$$ positions.
