WebAP Statistics 2024 Formulas and Tables Sheet *S tandard deviation is a measurement of variability from the theoretical population. Standard error is the estimate of the standard … WebZ = X − μ σ. is a standard normal random variable—it is normal with mean 0 and standard deviation 1. Note that this is the formula used to compute the z -score of a normal random variable! Since we can turn any normal random variable into a standard normal random variable, we only need one table of values! Yay!

A negative z-score means it's lower than average. You can also determine the percentage of the population that lies above or below any z-score using a z-score table. baking recipes
