Common Student Errors

• Students often struggle with using the correct notation. They will use mu when they mean xbar or forget subscripts when describing the mean and standard deviation of the sampling distribution. Don't let this slide! Getting comfortable with correct notation now will benefit students greatly later in the course.

• For normal distribution calculations with a sampling distribution of a sample mean, students will incorrectly use sigma as the standard deviation instead of sigma/sqrt(n). Remind students that the normal distribution they are working with is the sampling distribution, not the population distribution.

• 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.
