1. I chose Life Expectancy 2020 (Excel) from Hawkes Stat. 2. The variable dataset used to create this Excel spreadsheet is called rank. The variable is ordinal, representing an ordered position but the differences between ranks are not meaningful in a numerical sense. I used rank 1 - rank 140 as an example, where 1-20 with the highest life expectancy. There is a class limit because a lower class defines the smallest rank in a category while the upper-class limits define the highest rank. There is cumulative relative frequency because it shows the proportion of countries which has a rank or are below a certain threshold. • • • 1-20 (Top 20 countries with the highest life expectancy) 21-40 41 - 60 • 61-80 • 81-100 • 101-120 • - 121 140 (Lowest life expectancy group)
