variance

Among the world's richest nations, there is much variance in the prioritization of education. Here we look at the relationship between this wealth, and the quality of schooling in each country.

The school life expectancy measures the number of years of schooling a child can expect to receive, while the expenditure on education allows us to compare how much money each country dedicates to teaching their youth.

There's no secret that different types of websites attract different levels and types of advertisers - but the variance is rarely elaborated upon.
