I've a chart where I'm graphing how much the top 1% of political contributors (the 99th percentile) donate, vs the rest. You can see the graph here, by clicking on "View by" in the top-right corner, and selecting "Percentile." If done correctly, you should get this view.

Technically, "Percentile" is not the right word (and it's the term I'm asking about in this question---how to replace it), since what is known colloquially as "The 1%" is actually the 99th percentile; hence, I'm not sure how to navigate colloquial understanding vs. the correct understanding.

So, what's the correct term for that "View by" entry?

    What's wrong with the top 1%? – Gary Apr 23 '17 at 5:11

    Presumably if we were talking about the top 10% we would say "the top decile", or the top 25% - "the top quartile". So, for the top 1% I presume it is the top *centile". But it is not a term I have seen much used. – WS2 Apr 23 '17 at 6:38

Percentile (Wikipedia)

A percentile (or a centile) is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. For example, the 20th percentile is the value (or score) below which 20% of the observations may be found.

As Gary notes in a comment, there's also the top 1 percent.

  • I ended up keeping "Percentile" for the View, and adding "Top 1%" and "Bottom 99%" to the legend. – Khashir Apr 23 '17 at 22:44

Presumably if we were talking about the top 10% we would say "the top decile", or the top 25% - "the top quartile".

So, for the top 1% it is the *the top centile". But that term is less common than percentile.

Indeed the ODO defines centile as "another word for percentile"
