This seems less clear than saying "greater." Am I missing something?

Yes, but why is it useful? Why should the reader keep going?

Full what?

Title says "Relative Odds" and then the article uses "relative likelihood" to describe the same concept. That's confusing.

The title says "Frequency Diagrams" and then never defines it in the article's body. Elsewhere on the internet, it's referred to as as frequency box or geometric visualization, while frequency diagrams are line-charts.
