[Corpora-List] Distribution of errors in dictations

[Ana Julia Perrotti-Garcia]

Brett

your question reminded me of the altitude maps, that give us a quick idea about flat surfaces and mountains. What about creating a 4-color scale (green-yellow-orange-red)? Green could stand for error-free words that are followed by no error ; yellow  could stand for error-free words that are followed by an error; red could stand for error words that are followed by another error word, and so on (maybe it could have some more colors).
I really don't know if this is feasiblem but if it works, you 'll end with a visual scale that may help detecting word relations that number are not always able to show.

Kind regards,

  In our EAP program, we include dictation as part of our listening assessment. One thing I've noticed is that errors seem to cluster together. I'd like to see if this is more than just a vague impression from marking too many tests. What kind of tools and statistics might be used to show whether something's happening here? 


  I suppose one thing I could do is simply count the number of error-free words that are followed by an error and compare that to the number of errors that are followed by an error. I remember though some ways for measuring "burstiness", and I wonder if that might be relevant. Any thoughts?


  Best,
  Brett
