The results of Lertap's RSA run for this test are captured below.  Four items were excluded from the analysis as their correct answers were selected by fewer students than found for one or more of the distractors (items I2, I12, I14, and I20).

 

It took 34 seconds to process the data.

 

   

 

   

 

Nine student pairs were found by Lertap RSA to have "very suspect" responses.
