Overall the quiz went well.  Students did well calculating percentiles and z-scores.  Where they lost the most points were with the interpretations and conclusions, partially because they often left them off completely.  We find that when questions ask a student to do more than one thing it is easy for the them to only complete the computation portion and not the interpretation.  We saw this with a question that asked students to find and interpret a z-score.  Many students only calculated and didn’t interpret.  Work hard to break this habit early.
