webspace.ship.eduFor example: We have a sample that has a mean of 8 and a standard deviation of 2.53. What is the z-score of an observation from this data set that has a value of 13? Therefore, a value of 13 in this data set is 1.98 standard deviations from the mean. We can use the z-table to find out the probability of picking a number >= 13 from this data set.
