A z-score tells us how many standard deviations away a given value is from the mean. The z-score of a given value is calculated as: z-score = (x – μ) / σ. where: x: individual value. μ: population mean. σ: population standard deviation. This tutorial explains how to calculate z-scores on a TI-84 calculator.A standard observation is used to determine how many standard deviations the original observation falls from the mean. 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. On TI-84 Plus C Silver Edition, the area under the standard normal curve for a z-value ...The sum of all these squared differences is then divided by the number of data points in the set.

A 1 in a z-score means 1 standard deviation, not 1 unit. So if the standard deviation of the data set is 1.69, a z-score of 1 would mean that the data point is 1.69 units above the mean. In Sal's example, the z-score of the data point is -0.59, meaning the point is approximately 0.59 standard deviations, or 1 unit, below the ...
