Quartiles are used to compute theinterquartile range— a measure ofvariabilityaround the median. The interquartile range is obtained by subtracting the first quartile from the third quartile: Q3 – Q1. It represents the range of the middle half of the data, providing insights into the overall ...
As nouns the difference between quantile and quartile is that quantile is (statistics) one of the class of values of a variate which divides the members of a batch or sample into equal-sized subgroups of adjacent values or a probability distribution into
Quantiles are cut points dividing the range of a probability distribution into continuous intervals with equal probabilities, while quartiles divide data into quarters.
In a normal distribution, 7% of the items are under 35 and 89% are under 63. What are the the mean and standard deviation of the distribution? The standard deviation of a normal distribution is 12 and 90% of the values are greater than 6. What is the value of the mean?

Tertiles divide data into three equal parts; quartiles divide data into four. Both are statistical measures of spread.
