It's a line plot of the cumulative frequency.
Here's an example link: http://home.ched.coventry.ac.uk/Volume/vol0/ogive.htm
Okay I've also been very confused on ogives ..the cumulative average concept. Is there a site that gives tutorials on them? b/c I cannot seem to find any. I'm very confused on how to do them especially calculating it from a graph, and I think I need tutorials first before I do problems, so yea. Please advise thank you!!!
