Compare observations between dissimilar variables. Identify outliers. Calculate probabilities and percentiles using the standard normal distribution. In this post, I cover all these uses for z-scores along with using z-tables, z-score calculators, and I show you how to do it all in Excel.
Z tables are typically composed as follows: The label for rows contains the integer part and the first decimal place of Z. The label for columns contains the second decimal place of Z. The values within the table are the probabilities corresponding to the table type.

To use the z-score table, start on the left side of the table and go down to 1.2. At the top of the table, go to 0.05. This corresponds to the value of 1.2 + .05 = 1.25. The value in the table is .8944 which is the probability. Roughly 89.44 percent of people scored worse than Zoe on the ACT.
