# Z-Score Calculator

The calculator will find the Z-Score (standardized score), given the unstandardized value, mean and standard deviation of the population, with steps shown.

Population mean: $$\mu=$$$Population standard deviation: $$\sigma=$$$
Value: $$x=$$$If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below. ## Solution Your input: find the z-score of $$x=2$$$ with $$\mu = \frac{3}{2}$$$and $$\sigma = \frac{2}{5}$$$.
$$z=\frac{x-\mu}{\sigma}=\frac{2-\frac{3}{2}}{\frac{2}{5}}=\frac{5}{4}$$$. Answer: the z-score is $$z=\frac{5}{4}$$$.
