What is an average bounce rate

Question: I wondered whether you might be able to point me in the direction of some info on web behaviour? We've recently been looking at “drop off” rates for some of our online content and seeing if we can compare it with external sites to help gauge whether the behaviours we are seeing could be considered as 'typical'. The metrics we've been looking at include time spent on a page (0-10, 10-20 seconds etc) and would like to compare to external websites such as BBC, YouTube, etc. Do you know how it is possible to obtain this data, or any external websites who may have it? We measure it, but have no external reference as to whether it is good, bad or indifferent. Nicola
