CDF

A Cumulative Distribution Function (CDF) is a tool used in statistics that describes the likelihood of a random variable being less than or equal to a specific value. It provides a way to see how probabilities accumulate across different outcomes. For example, if you’re looking at test scores, the CDF would show the percentage of students scoring below any given point. It helps to understand the overall distribution of data and to compare different datasets efficiently. Essentially, the CDF maps each value to its cumulative probability, giving a complete picture of how data values are spread out.
