<DIV><FONT face=Arial><FONT size=2><FONT size=+0>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</FONT> could
stand for <FONT face="Times New Roman" size=3>error-free words that are followed
by an error; red <FONT face=Arial size=2>could stand for </FONT><FONT
face="Times New Roman" size=3>error words that are followed by another error
word, and so on (maybe it could have some more
colors).</FONT></FONT></FONT></FONT></DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [Corpora-List] Distribution of
errors in dictations</DIV>
<DIV><BR></DIV>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?
<DIV><BR></DIV>
<DIV>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?<BR><BR>
