Mean Median Mode Variance Standard Deviation Examples. The variance of a sample data is the the mean square deviation of the data points from the sample. A samples standard deviation measures the average amount of variation in that sample. Equation ref31 is another common method for calculating sample standard deviation although it is an bias estimate. Write a table that subtracts the mean from each observed value.

Converting z-scores into Percentiles. A standard deviation is used to tell how the numbers for a group of numbers are spread out from the average mean. Mean 55 Example z-score.
