  1. Why are there no negative values in the z table?
  2. If you were given an individual’s raw score and it was above the mean, what steps would you take to determine that individual’s percentile? What if their raw score was below the mean?
  3. If you were given an individual’s z score and it was less than zero, what steps would you take to determine that individual’s raw score?
  4. How is the process of determining percentiles different if you were given a sample mean rather than an individual raw score?
