Empirical Distribution Function

The Empirical Distribution Function (EDF) is a way to represent how a set of data points are distributed. It calculates the proportion of observations that fall below or equal to a particular value. For example, if you have test scores for a class, the EDF tells you what fraction of students scored below any given score. By plotting this information, you can visualize the overall distribution of the data and understand trends, such as where most scores lie or how spread out they are. It's a useful tool in statistics for analyzing and interpreting data sets.
