d3.js - quantile vs quartile in lay terms -

my limited understanding quantile , quartile sort of similar totally different ways of measurement. googled not find easy understand explanation. there d3 related question here no reply yet.

my specific question when should utilize quantile instead of quartile or vice versa? appreciate lay term explanation or trivial example. thanks!

the cumulative density function gives probability of random variable beingness on or below value.

the quantile function opposite of that. i.e. give probability , tells random variable value.

so median value of quantile @ probability value of 0.5.

a quartile value of quantile @ probabilities 0.25, 0.5 , 0.75.

so, in general, can utilize quantile. quartile special case.

d3.js statistics quantile
