_______ are the values dividing up the distribution or data set of ordered data values of a variable into equal parts.

Please fill in the blank: 

Though, the corresponding function in R allows us to find any specific list of values.  The code below can be copied into any R window one line at a time.  Please do so and make note of the resulting output and how it relates to this lecture.

Sample R Code:

---

x <- rnorm(250)
hist(x)
quantile(x)
quantile(x,probs=seq(0,1,0.25))
quantile(x,probs=seq(0,1,0.1))
quantile(x,probs=seq(0,1,0.2))
quantile(x,probs=c(0.01,0.02,0.05,0.1,0.9,0.95,0.98,0.99))
