Common Student Errors
When doing normal distribution calculations, students often forget what must be included for full credit. We suggest requiring a picture to be drawn and labeled, work shown with a z-score calculation, and then a final answer.
When calculating an area to the right of a boundary value, students often forget to subtract the area in Table A away from 1.
When using Table A to find a percentile (area), students often incorrectly find the value in the left column (z-score), when they should be looking at the body of the table.
Students sometimes assume that all distributions are normal distributions. If you give them a problem with a uniform density curve, they should not be using Table A to find areas.
