2010 – Demographics (who were your subjects)? I assume you obtained consent?   You should only compute the descriptive stats that are relevant (almost never compute mean, median AND mode on the same measure, eg). Good recommendations. A- + LATE = B-

4382 – Demographics (who were your subjects)? I assume you obtained consent? How did you define 'error'? You should only compute the descriptive stats that are relevant (almost never compute mean, median AND mode on the same measure, eg). B+

6611 – Great job all around, and way beyond requirements on tasks. Good summary and recommendations. A+

Could have described your definition of 'error', maybe some demographics, and interpretation of your results. I know there are only two samples, but could have done some descriptive stats. A-

8017 – Good description and recommendations. You should only compute the descriptive stats that are relevant (almost never compute mean, median AND mode on the same measure, eg). (fyi, actually better to not have tasks be ambiguous, since it introduces unnecessary error variance into your data). A-
