How To Calculate The formula for calculating a z score is z x where x is the raw score is the population mean and is the population standard deviation As the formula shows the z score is simply the raw score minus the population mean divided by the population standard deviation Figure 2 The formula for finding z-scores is the following: X represents the data point of interest. Mu and sigma represent the mean and standard deviation for the population from which you drew your sample. Alternatively, use the sample mean and standard deviation when you do not know the population values.

Z Score FormulaRyan Giglio 5 years ago When I paused to calculate the standard deviation myself, I came up with 1.83, not 1.69. It looks like Sal got 1.69 by taking the sqrt of the biased sample variance instead of the unbiased sample variance, which we were taught to do in the previous videos. Why is this? • ( 12 votes) Ryan Giglio 5 years ago Z x For example let s say you have a test score of 190 The test has a mean of 150 and a standard deviation of 25 Assuming a normal distribution your z score would be z x 190 150 25 1 6 The z score tells you how many standard deviations from the mean your score is
