Choose measures for center and spread
Consider the density plots shown here. What are the most appropriate measures to describe their centers and spreads? In this exercise, you'll select the measures and then calculate them.
This exercise is part of the course
Exploratory Data Analysis in R
Exercise instructions
Using the shapes of the density plots, calculate the most appropriate measures of center and spread for the following:
- The distribution of life expectancy in the countries of the Americas. Note you'll need to apply a filter here.
- The distribution of country populations across the entire
gap2007dataset.
