While both the Bits/s columns in the Statistics -> Conversations window, and the Bits/s column of the Statistics -> Protocol Hierarchy window suffer from rounding errors, they do in fact measure the average Bits/s of all the packets for the time duration of the capture file, as seen in the Statistics -> Capture File Properties window.
On the other hand, the Statistics -> I/O Graph plots Bits/s averaged over whatever the chosen plotting time interval is that's selected. By default, the interval is "1 sec"; therefore, for every second of time that has elapsed in the capture file, the graph is displaying the average value for that particular 1 second interval, and that is repeated for every such interval. This is not the same as an average for the entire duration.
