The complexity of the code will depend upon how reliable your participants are. If you trust them, then all you need to do is to look at

played. start(0)

and

played.end(0)

. This will give you the time range for audio/video the first time it was played.
If you think they'll skip ahead and listed to only parts of it. You can use the played attribute to see how many time they stopped/paused.

element.played

will return the number of times they did this. You can then iterate over

start 

and

end 

to figure out whether they listened to entire clip or not.

Hi Ahmed,
Thank you so much for responding to my question. I'm very new to Javascript. Can you give an example code for using played.start(0) and played.end(0) and element.played so I can see how you would set up.
Thank you so much for your help. I really appreciate it!
Larisa
