Z-scores can be looked up in a table (z-table) to find the area under the standard normal curve (or probability) to the left of the z-value. Z-scores can be looked up in a table (z-table) to find the area under the standard normal curve (or probability) to the left of the z-value. Positive score in Z-Table represents the corresponding values that are greater than the mean. Table entries for z define the area under the standard normal curve to the left of the Z. Where x is the observation, m is the mean and s is standard deviation.Ī standard observation is used to determine how many standard deviations the original observation falls from the mean. You can use this Positive Z Score Table to find the values that are right of the mean.
