Quantile function

The quantile function is a tool in statistics that helps identify the value below which a certain percentage of data falls. For example, it can tell you the score below which 25% of students scored, or the median (50th percentile). Essentially, it helps you understand the distribution of data by pinpointing values at specific cutoff points. It’s useful for summarizing and comparing data, making it easier to see how values are spread out within a dataset. The quantile function complements other statistical measures, providing insights into data distribution and variability.
