This sounds like a simple question and I know PDF graphs are used a lot in presentations and financial publications. Yet, what information does it actually provide? The CDF actually gives you probabilities of the random variable falling within a certain range. The PDF does not tell you the probability of a particular random variable of occurring (that is 0). It also doesn't tell you the probability of a range of random variables occurring (you'll need to do an integral for that). I can't think of any information a PDF would tell you that a CDF can't, yet I rarely/almost never see CDFs in presentations or financial publications.
What am I missing here? What information should I discern when I look at a PDF?
