Percentile Quantile Decile Quartile

[MissYiota]

Someone to clarify to what each of this terms corresponds exactly ? and what if one refers to the 2nd decile or the 3rd quantile ?
Percentile: you divide your population or sample by 100%. So the 12 percentile is 12% and the 4th percentile is 4% ?
Quintile ?
Decile ?
Quantile ?
Quartile ?

 

[MissYiota]

never mind, got it. just have to divide by 100 depending on what you have.
Just know that quintile is 5, decile 10, quartile 4 percentile 100 and the mediane for the most common one

 

[AndyNZ]

Quintile - divide population by 5
Decile - divide population by 10
Quantile - just refers to a point that you have used to divide up a population
Quartile - divide population by 4

The 2-quantile is called the median
The 3-quantiles are called tertiles or terciles → T
The 4-quantiles are called quartiles → Q
The 5-quantiles are called quintiles → QU
The 6-quantiles are called sextiles → S
The 10-quantiles are called deciles → D
The 12-quantiles are called duo-deciles → Dd
The 20-quantiles are called vigintiles → V
The 100-quantiles are called percentiles → P
The 1000-quantiles are called permilles → Pr
P
