Why are there no negative values in the z table?
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?
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?
How is the process of determining percentiles different if you were given a sample mean rather than an individual raw score?

1. See “Content/Distribution Tables/Z table - 0 to Z” to answer the following questions. The values of probability, or area from 0 to Z, for negative value of Z is the same as given for positive Z by symmetry, i.e., the table values are for + and – values of Z. Don’t forget the area of the left and right half of the normal distribution is .5. See Normal Distribution & Z Values in Videos-Topics In Stat 200 for examples....
