Answer:
Quantiles are cut points dividing the range of the data into contiguous intervals with equal probabilities. Certain quantiles are particularly important: The median of a data set divides the data into two equal parts: the bottom 50% and the top 50%. Quartiles divide the data four equal parts and percentiles divide it into hundredths, or 100 equal parts. Note that the median is also the 50th percentile. Deciles divide a data set into tenths (10 equal parts), and the quintiles divide a data set into fifths (5 equal parts). There is always one less quantile than the number of groups created (e.g. There are 3 quartiles dividing the data into 4 equal parts!)
