Calculadora de valor Z

Calcular puntuaciones z paso a paso

La calculadora encontrará el valor z (puntuación estandarizada) dado el valor sin estandarizar, la media y la desviación estándar de la población, con los pasos mostrados.

Enter your data or

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 contact us.

Solution

Your input: find the z-score of $$$x=2$$$ with $$$\mu = \frac{3}{2}$$$ and $$$\sigma = \frac{2}{5}$$$.

Z-score is calculated according to the following formula:

$$$z=\frac{x-\mu}{\sigma}=\frac{2-\frac{3}{2}}{\frac{2}{5}}=\frac{5}{4}$$$.

Answer: the z-score is $$$z=\frac{5}{4}=1.25$$$.
