Can a distribution have two medians
For any real-valued probability distribution with cumulative distribution function F, a median is defined as any real number m that satisfies the inequalities An equivalent phrasing uses a random variable X distributed according to F: Note that this definition does not require X to have an absolutely continuous distribution (which has a probability density function f), nor does it require a discrete one. In the former case, the inequali… WebVideo transcript. - [Instructor] What we're going to do in this video is start to compare distributions.
