The term PDV is defined in ITU-T Recommendation Y.1540, Internet protocol data communication service - IP packet transfer and availability performance parameters, section 6.2.
In this document we will avoid the term "jitter" whenever possible and stick to delay variation which is more precise.
It is also possible to visualize (I)PDV measurements, which makes interpreting and understanding the network easier, or (for bigger datasets) possible at all.
Another type are distribution histograms which are more useful for bigger datasets or even comparisons of different paths or technologies.
The effects of PDV in multimedia streams can be mitigated by a properly sized buffer at the receiver.
